soc/intel/alderlake: Enable CPPCv3

The patch defines the following helper functions:

get_cpu_scaling_factor(): Returns scaling factors of big and small core.

cpu_is_nominal_freq_supported(): Returns true if CPU supports Nominal
Frequency, otherwise false.

cpu_is_nominal_freq_supported(): Check CPU supports nominal frequency or
not.

The patch also enables CPPCv3 support for Intel Alder Lake which is
based on hybrid core architecture.

TEST=Verified Nominal Frequency and Nominal Performance are getting
updated for ADL-P small and big cores correctly.
