soc/intel/common/cpu: Use SoC overrides to set CPU privilege level
This patch implements a SoC overrides to set CPU privilege level
as the MSR is not consistent across platforms. For example:
On APL/GLK/DNV, it's MSR 0x120 and CNL onwards it's MSR 0x151.
BUG=b:233199592
TEST=Build and boot google/taeko to ChromeOS.
