cpufreq: Move CPPC configs to common Kconfig and add RISC-V

Browse source 
CPPC related config options are currently defined only in ARM specific
file. However, they are required for RISC-V as well. Instead of creating
a new Kconfig.riscv file and duplicating them, move them to the common
Kconfig file and enable RISC-V too.

This adds a CPUFreq driver which uses CPPC methods
as described in the ACPIv5.1 spec. CPPC stands for
Collaborative Processor Performance Controls. It
is based on an abstract continuous scale of CPU
performance values which allows the remote power
processor to flexibly optimize for power and
performance. CPPC relies on power management firmware
support for its operation.

This extends frequency invariance support in the CPPC cpufreq driver,
by using CPPC delivered and reference performance counters.
