Laszlo Ersek 089285b42c Revert "UefiCpuPkg/CpuDxe: Fix boot error" 
This reverts commit cee5b0441a.

Commit cee5b0441a ("UefiCpuPkg/CpuDxe: Fix boot error", 2020-12-08)
breaks CpuDxe (and with it, OVMF boot) on AMD processors. AMD processors
cannot do far jumps to 64-bit targets, as documented in the AMD64
Architecture Programmer's Manual.

Revert the patch until a RETFQ-based substitute is posted.
