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

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.
