Hao A Wu d148a178c1 Revert UefiCpuPkg/MpInitLib: Relocate microcode patch fields in CPU_MP_DATA
This reverts commit 88bd066166.

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2465

Commit 88bd066166 relocates the 'MicrocodePatchAddress' and
'MicrocodePatchRegionSize' fields in structure CPU_MP_DATA to ensure that
they can be properly passed between different architectures.

However, such change is not backward compatible with the scenario like
pre-existing binaries such as FSP. These binaries are built when the code
base has a different version of the CPU_MP_DATA structure definition. This
may cause issues when accessing the 'MicrocodePatchAddress' and
'MicrocodePatchRegionSize' fields, since their offsets are different
(between PEI phase in the FSP binaries and DXE phase in current code
implementation).
