soc/intel/common: Untie PRMRR from SGX
PRMRR is used by many Intel SOC features, not just Intel SGX.
As of now SGX and Key Locker are the features that need PRMRR.
Untie it from Intel SGX specific files and move to common cpulib.
Also rename PRMRR size config option. Use the renamed PRMRR size
config option to set the PRMRR size.
TEST=Able to set PRMRR size using config.
