Internal:
A quick update of V2 with the feedback received today.
Also, cc'd a wider range of people.
Looking forward to further discussion and feedback.
-----------------
External:
CPPC feedback counters can be unchanged or 0 when cores are idle, e.g.
clock-gated or power-gated. In such case, get the latest desired perf for
calculating frequency. Also, the HiSilicon CPPC workaround is now handled
by the common code and can be removed.

cppc_cpufreq: Return desired perf in ->get() if feedback counters are
0
cppc_cpufreq: Return latest desired perf if feedback counters don't
change
cppc_cpufreq: Remove HiSilicon CPPC workaround
