Revert "UefiCpuPkg/CpuDxe: Fix boot error"
This reverts commit cee5b0441af39dd6f76cc4e0447a1c7f788cbb00.
Commit cee5b0441af3 ("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.
