UefiCpuPkg/PiSmmCpuDxeSmm: Remove MTRR field from PSD
https://bugzilla.tianocore.org/show_bug.cgi?id=277
The MTRR field was removed from PROCESS_SMM_DESCRIPTOR
structure in commit:
https://github.com/tianocore/edk2/commit/26ab5ac3621bdefe96987f8c1512ca79e1bb7ac0
However, the references to the MTRR field in assembly
files were not removed. Remove the extern reference
to gSmiMtrr and set the Reserved14 field
of PROCESS_SMM_DESCRIPTOR to 0.
