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.

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 endpoint id assigned to the modem LAN RX endpoint for the SC7180 SoC
is incorrect. The erroneous value might have been copied from SDM845 and
never updated. The correct endpoint id to use for this SoC is 11.

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.
