soc/intel/common/cpu: Use SoC overrides to drop CPU privilege level

This patch implements a SoC overrides to drop CPU privilege level
as the MSR is not unique across different CPUs.

For example: On APL/GLK, its MSR 0x120 and CNL onwards its MSR 0x151.

For now, only APL SoC has implemented the overrides.
