Ruiyu Ni 60cb4d1b04 UefiCpuPkg/CpuCommonFeatures: Follow SDM for MAX CPUID feature detect
According to IA manual:
"Before setting this bit (MSR_IA32_MISC_ENABLE[22]) , BIOS must
execute the CPUID.0H and examine the maximum value returned in
EAX[7:0]. If the maximum value is greater than 2, this bit is
supported."

We need to fix our current detection logic to compare against 2.
