[Patch v2] UefiCpuPkg RegisterCpuFeaturesLib: Fix buffer pointer error usage.

[Eric Dong <eric.dong@intel.com>]

Current code allocate buffer for the pointer which later get value
from PCD database. but current code error use "=" for this case.
Use AllocateCopyPool instead to fix it.

V2 enhanced to directly use AllocateCopyPool to get the PCD value.
