firmware: arm_scmi: Add v3.2 perf level indexing mode support
SCMI v3.2 adds PERF protocol support to optionally define performance
domains that cannot be represented on a linear scale; the platform firmware
can declare the performance levels of a domain as being 'level indexed' and
provide an indicative frequency associated to each of those levels, with
such indexes not required anymore to be contiguous nor to satisfy any
linear-scaling constraint: when level-indexing is available for a domain,
the platform will expect to deal with SCMI requests using indexes instead
of performance levels for that domain.
Add level-indexing mode support to the PERF protocol implementation while
maintaining unchanged the protocol operations interface exposed by PERF;
all the required mapping from performamce levels/frequencies to the
corresponding level indexes is carried out transparently by the core PERF
protocol support: as a consequence no change is either required in any
SCMI driver using the PERF protocol, even when using level indexing.

Moving only one of the two files in drivers/soc/actions to drivers/genpd
caused a link failure in allmodconfig, as drivers/genpd is entered
for compile testing, but drivers/soc/actions accidentally got skipped:

memory: tegra: add check if MRQ_EMC_DVFS_LATENCY is supported
Add check to ensure that "MRQ_EMC_DVFS_LATENCY" is supported by the
BPMP-FW before making the MRQ request. Currently, if the BPMP-FW
doesn't support this MRQ, then the "tegra186_emc_probe" fails.
Due to this the Memory Interconnect initialization also doesn't
happen. Memory Interconnect is not dependent on this MRQ and can
initialize even when this MRQ is not supported in any platform.
The check ensures that the MRQ is called only when it is supported
by the BPMP-FW and Interconnect initializes independent of this MRQ.
Also, moved the code to new function for better readability.

size and corrupt data.

because that did not work correctly with a bug, and we agreed the
current '(fault)' output (instead of '"(fault)"' like a string)
explains what happened more clearly.
