Andy reported:
Debian clang version 19.1.7 is not happy when compiled with
`make W=1` (note, CONFIG_WERROR=y is the default):
ipmi_si_platform.c:268:15: error: cast to smaller integer type 'enum si_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
268 | io.si_type = (enum si_type)device_get_match_data(&pdev->dev);
The IPMI SI type is an enum that was cast into a pointer that was
then cast into an enum again. That's not the greatest style, so
instead create an info structure to hold the data and use that.

The caller of this function (parisc_driver_remove() in
arch/parisc/kernel/drivers.c) ignores the return value, so better don't
return any value at all to not wake wrong expectations in driver authors.
The only function that could return a non-zero value before was
ipmi_parisc_remove() which returns the return value of
ipmi_si_remove_by_dev(). Make this function return void, too, as for all
other callers the value is ignored, too.
Also fold in a small checkpatch fix for:
WARNING: Unnecessary space before function pointer arguments
+ void (*remove) (struct parisc_device *dev);

The ->addr_source_cleanup() callback is solely used by PCI driver
and only for one purpose, i.e. to disable device. Get rid of
->addr_source_cleanup() by switching to PCI managed API.

Instead of making the comparison one by one, reuse si_to_str[] array
in ipmi_hardcode_init_one() in conjunction with match_string() API.

ipmi_si_sm.h was getting included in lots of places it didn't
belong. Rework things a bit to remove all the dependencies,
mostly just moving things between include files that were in
the wrong place and removing bogus includes.

When a hotmod-added device is removed or when the module is removed,
remove the platform devices that was created for it.

It was being done in two different places now that hard-coded devices
use platform devices, and it's about to be three with hotmod switching
to platform devices. So put the code in one place.
This required some rework on some interfaces to make the type space
clean.

When excuting a command like:
modprobe ipmi_si ports=0xffc0e3 type=bt
The system would get an oops.
The trouble here is that ipmi_si_hardcode_find_bmc() is called before
ipmi_si_platform_init(), but initialization of the hard-coded device
creates an IPMI platform device, which won't be initialized yet.
The real trouble is that hard-coded devices aren't created with
any device, and the fixup is done later. So do it right, create the
hard-coded devices as normal platform devices.
This required adding some new resource types to the IPMI platform
code for passing information required by the hard-coded device
and adding some code to remove the hard-coded platform devices
on module removal.
To enforce the "hard-coded devices passed by the user take priority
over firmware devices" rule, some special code was added to check
and see if a hard-coded device already exists.

Instead of allocating the smi_info structure, filling in the I/O
info, and passing it to ipmi_si_add_smi(), just pass the I/O
info in the io structure and let ipmi_si_add_smi() allocate
the smi_info structure.
This required redoing the way the remove functions for some
device interfaces worked, a new function named
ipmi_si_remove_by_dev() allows the device to be passed in and
detected instead of using driver data, which couldn't be
filled out easily othersize.
After this the platform handling should be decoupled from the
smi_info structure and that handling can be pulled out to its
own files.

So the platform code can do it without having to access the
smi info, getting ready for pulling the platform handling
section to their own files.
