This is to prevent #DB interception on SEV-ES VM with
enabled DebugSwap feature, more details in 3/5.

This is based on sha1 dd3ba82d31a6 and pushed out at
https://github.com/aik/edk2/commits/debugswap

The corresponding Linux change (HV and VM) is here:
https://github.com/aik/linux/commits/debugswap
and has just been posted to lkml/etc as
"[PATCH kernel 0/3] KVM: SEV: Enable AMD SEV-ES DebugSwap"

Please comment. Thanks.
