Finally, rename "ipa_clock.c" to be "ipa_power.c" and "ipa_clock.h"
to be "ipa_power.h".

There are only a few remaining spots that validate IPA code
conditional on whether a symbol is defined at compile time.
The checks are not expensive, so just build them always.
This completes the removal of all CONFIG_VALIDATE/CONFIG_VALIDATION
IPA code.

Add IPA device attributes to expose information known by the IPA
driver about the hardware and its configuration.
All pointers used to display these attribute values (i.e., IPA
pointer and endpoint pointers) will have been initialized by the
time IPA probe has completed, so they may be safely dereferenced.

Add support for the SDX55 SoC, which includes IPA version 4.5.
Starting with IPA v4.5, a few of the memory regions have a different
number of "canary" values; update comments in the where the region
identifers are defined to accurately reflect that.
I'll note three differences in SDX55 versus the other two existing
platforms (SDM845 and SC7180):
- SDX55 uses a 32-bit Linux kernel
- SDX55 has four interconnects rather than three
- SDX55 uses IPA v4.5, which uses inline checksum offload

Rename the SC7180 configuration data file so that its name is
derived from its IPA version.
Update a few other references to the code that talk about the SC7180
rather than just IPA v4.2.

Rename the SDM845 configuration data file so that its name is
derived from its IPA version. I am not aware of any special IPA
behavior or handling that would be based on a specific SoC (as
opposed to a specific version of the IPA it contains).
Update a few other references to the code that talk about the SDM845
rather than just IPA v3.5.1.
