Populate the core clock rate and interconnect average and peak
bandwidth data for SDM845 and SC7180 in their configuration data
files. At this point we still don't *use* this data.
Note that SC7180 actually defines a new core clock rate (100 MHz
instead of 75 MHz) and new interconnect bandwidth values. They
will be activated in the next commit, which uses the configured
values rather than the fixed constants.

I have discovered that the maximum number of source packet contexts
configured for SDM845 is incorrect. Fix this error.

The IPA hardware manages various resources (e.g. descriptors)
internally to perform its functions. The resources are grouped,
allowing different endpoints to use separate resource pools. This
way one group of endpoints can be configured to operate unaffected
by the resource use of endpoints in a different group.
Endpoints should be assigned to a resource group, but we currently
don't do that.
Define a new resource_group field in the endpoint configuration
data, and use it to assign the proper resource group to use for
each AP endpoint.

The AP LAN RX endpoint should not have download checksum offload
enabled.
The receive handler does properly accommodate the trailer that's
added by the hardware, but we ignore it.

A "delay mode" feature was put in place to work around a problem
that was observed during development of the upstream IPA driver. It
used TX endpoint "delay mode" in order to prevent transmitting
packets toward the modem before it was ready.
A race condition that would explain the problem has long since been
fixed, and we have concluded that the "delay mode" feature is no
longer required. So get rid of it.

Arrange to use an item from SMEM memory for IPA. SMEM item number
497 is designated to be used by the IPA. Specify the item ID and
size of the region in platform configuration data. Allocate and get
a pointer to this region from ipa_mem_init(). The memory must be
mapped for access through an SMMU.

Define a region of IMEM memory available for use by IPA in the
platform configuration data. Initialize it from ipa_mem_init().

The ipa_mem_data structure type was never actually used. Instead,
the IPA memory regions were defined using the ipa_mem structure.
Redefine struct ipa_mem_data so it encapsulates the array of IPA-local
memory region descriptors along with the count of entries in that
array. Pass just an ipa_mem structure pointer to ipa_mem_init().
Rename the ipa_mem_data[] array ipa_mem_local_data[] to emphasize
that the memory regions it defines are IPA-local memory.

This patch defines configuration data that is used to specify some
of the details of IPA hardware supported by the driver. It is built
as Device Tree match data, discovered at boot time. The driver
supports the Qualcomm SDM845 SoC. Data for the Qualcomm SC7180 is
also defined here, but it is not yet completely supported.
