Rename a number of functions to clarify that there is no longer a
notion of an "IPA clock," but rather that the functions are more
generally related to IPA power management.
ipa_clock_enable() -> ipa_power_enable()
ipa_clock_disable() -> ipa_power_disable()
ipa_clock_rate() -> ipa_core_clock_rate()
ipa_clock_init() -> ipa_power_init()
ipa_clock_exit() -> ipa_power_exit()
Rename the ipa_clock structure to be ipa_power. Rename all
variables and fields using that structure type "power" rather
than "clock".
Rename the ipa_clock_data structure to be ipa_power_data, and more
broadly, just substitute "power" for "clock" in places that
previously represented things related to the "IPA clock".
Update comments throughout.

Finally the code handles the IPA memory region array in the
configuration data without assuming it is indexed by region ID.
Get rid of the array index designators where these arrays are
initialized. As a result, there's no more need to define an
explicitly undefined memory region ID, so get rid of that.
Change ipa_mem_find() so it no longer assumes the ipa->mem[] array
is indexed by memory region ID. Instead, have it search the array
for the entry having the requested memory ID, and return the address
of the descriptor if found. Otherwise return NULL.
Stop allowing memory regions to be defined with zero size and zero
canary value. Check for this condition in ipa_mem_valid_one().
As a result, it is not necessary to check for this case in
ipa_mem_config().
Finally, there is no need for IPA_MEM_UNDEFINED to be defined any
more, so get rid of it.

Store the memory region ID in the memory descriptor structure. This
is a move toward *not* indexing the array by the ID, but for now we
must still specify those index values. Define an explicitly
undefined region ID, value 0, so uninitialized entries in the array
won't use an otherwise valid ID.

On IPA v3.5.1, the sequencer type for the modem TX endpoint does not
define the replication portion in the same way the downstream code
does. This difference doesn't affect the behavior of the upstream
code, but I'd prefer the two code bases use the same configuration
value here.

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.
