[PATCH v1 5/5] cpufreq: CPPC: Enable dvfs_possible_from_any_cpu

[Pierre Gondois <pierre.gondois@arm.com>]

From: Pierre Gondois <Pierre.Gondois@arm.com>

The communication mean of the _CPC desired performance can be
PCC, System Memory, System IO, or Functional Fixed Hardware (FFH).

PCC, SystemMemory and SystemIo address spaces are available from any
CPU. Thus, dvfs_possible_from_any_cpu should be enabled in such case.
For FFH, let the FFH implementation do smp_call_function_*() calls.
