xieyuanh 33e31c289c UefiCpuPkg/MpInitLib: Update the comments of _CPU_MP_DATA.
No functional changes in this patch.

Updates the comments of _CPU_MP_DATA to delcared that duplications in
CpuMpData are present to avoid to be direct accessed and comprehended
 in assembly code. CpuMpData: Intended for use in C code while
 ExchangeInfo are used in assembly code in this module.

This patch deletes the unnecessary comments in CpuMpData, since
CpuMpData is no longer responsible for passing information from PEI to
DXE.
