This is the first of cleanup for SEV MemEncryptLib. The library uses
the CPUID followed by the MSR read to determine whether SEV is enabled.
Now that we have a workarea concept, the logic can be simplified to
store the msr status in workarea and use that to build PCDs and then
later simply use the PCDs instead of going through the CPUID and RDMSR.
The complete branch is available at

Brijesh Singh (2):
OvmfPkg/ResetVector: cache the SEV status MSR value in workarea
OvmfPkg/BaseMemEncryptLib: use the SEV_STATUS MSR value from workarea
Looks good to me.

I ran into a regression for non-SEV guest, let me work to fix and post v2.
