Use the newly added of_reserved_mem_region_to_resource{_byname}()
functions to handle "memory-region" properties.
The error handling is a bit different for mtk_wed_mcu_load_firmware().
A failed match of the "memory-region-names" would skip the entry, but
then other errors in the lookup and retrieval of the address would not
skip the entry. However, that distinction is not really important.
Either the region is available and usable or it is not. So now, errors
from of_reserved_mem_region_to_resource() are ignored so the region is
simply skipped.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/net after the previous
conversion commits apart from the wireless drivers to use .remove(),
with the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

In "ipa_cmd.h", ipa_cmd_data_valid() is declared, but that function
does not exist. So delete that declaration.
Also, for some reason ipa_cmd_init() never gets called. It isn't
really critical--it just validates that some memory offsets and a
size can be represented in some register fields, and they won't fail
with current data. Regardless, call the function in ipa_probe().

Currently, enabling wakeup for the IPA device doesn't occur until
the setup phase of initialization (in ipa_power_setup()).
There is no need to delay doing that, however. We can conveniently
do it during the config phase, in ipa_interrupt_config(), where we
enable power management wakeup mode for the IPA interrupt.
Moving the device_init_wakeup() out of ipa_power_setup() leaves that
function empty, so it can just be eliminated.
Similarly, rearrange all of the matching inverse calls, disabling
device wakeup in ipa_interrupt_deconfig() and removing that function
as well.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

IPA register definitions have evolved with each new version. The
changes required to support more than 32 endpoints in IPA v5.0 made
it best to define a unified mechanism for defining registers and
their fields.
GSI register definitions, meanwhile, have remained fairly stable.
And even as the total number of IPA endpoints goes beyond 32, the
number of GSI channels on a given EE that underly endpoints still
remains 32 or less.
Despite that, GSI v3.0 (which is used with IPA v5.0) extends the
number of channels (and events) it supports to be about 256, and as
a result, many GSI register definitions must change significantly.
To address this, we'll use the same "ipa_reg" mechanism to define
the GSI registers.
As a first step in generalizing the "ipa_reg" to also support GSI
registers, isolate the definitions of the "ipa_reg" and "ipa_regs"
structure types (and some supporting macros) into a new header file,
and remove the "ipa_" and "IPA_" from symbol names.
Separate the IPA register ID validity checking from the generic
check that a register ID is in range. Aside from that, this is
intended to have no functional effect on the code.

The AP has third pulse generator available starting with IPA v5.0.
Redefine ipa_qtime_val() to support that possibility. Pass the IPA
pointer as an argument so the version can be determined. And stop
using the sign of the returned tick count to indicate which of two
pulse generators to use.
Instead, have the caller provide the address of a variable that will
hold the selected pulse generator for the Qtime value. And for
version 5.0, check whether the third pulse generator best represents
the time period.
Add code in ipa_qtime_config() to configure the fourth pulse
generator for IPA v5.0+; in that case configure both the third and
fourth pulse generators to use 10 msec granularity.
Consistently use "ticks" for local variables that represent a tick
count.

Introduce a new way of specifying how the GSI firmware gets loaded
for IPA. Currently, this is indicated by the presence or absence of
the Boolean "modem-init" Device Tree property. The new property
must have a value--either "self" or "modem"--which indicates whether
the AP or modem is the GSI firmware loader, respectively.
For legacy systems, the new property will not exist, and the
"modem-init" property will be used. For newer systems, the
"qcom,gsi-loader" property *must* exist, and must have one of the
two prescribed values. It is an error to have both properties
defined, and it is an error for the new property to have an

Prior to IPA v5.0, there could be no more than 32 endpoints.
A filter table begins with a bitmap indicating which endpoints have
a filter defined. That bitmap is currently assumed to fit in a
32-bit value.
Starting with IPA v5.0, more than 32 endpoints are supported, so
it's conceivable that a TX endpoint has an ID that exceeds 32.
Increase the size of the field representing endpoints that support
filtering to 64 bits. Rename the bitmap field "filtered".
Unlike other similar fields, we do not use an (arbitrarily long)
Linux bitmap for this purpose. The reason is that if a filter table
ever *did* need to support more than 64 TX endpoints, its format
would change in ways we can't anticipate.
Have ipa_endpoint_init() return a negative errno rather than a mask
that indicates which endpoints support filtering, and have that
function assign the "filtered" field directly.

A recent commit made disabling the SMP2P "setup ready" interrupt
unrelated to ipa_modem_stop(). Given that, it seems fitting to get
rid of ipa_modem_init() and ipa_modem_exit() (which are trivial
wrapper functions), and call ipa_smp2p_init() and ipa_smp2p_exit()
directly instead.
