soc/intel: Standardize names of common MSRs
Use defined name in Intel 64 and IA-32 Architectures Software Developer’s Manual. Renamed MSRs are (register address, register name): 0x35 MSR_CORE_THREAD_COUNT 0x121 MSR_EMULATE_PM_TIMER 0x1f4 MSR_PRMRR_PHYS_BASE 0x1f5 MSR_PRMRR_PHYS_MASK 0x2f4 MSR_UNCORE_PRMRR_PHYS_BASE 0x2f5 MSR_UNCORE_PRMRR_PHYS_MASK Change-Id: I53f11a2ce831456d598aa21303a817d18ac89bba Signed-off-by: Elyes HAOUAS <ehaouas@noos.fr> Reviewed-on: https://review.coreboot.org/c/30288 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Lijian Zhao <lijian.zhao@intel.com>
