[PATCH v3 00/13] Add GHCBv2 macro and helpers

["Brijesh Singh" <brijesh.singh@amd.com>]

This series is taken from the SNP RFC. This series defines the GHCBv2
macros and NAE events. Additionally, it also introduces a helper to
clear the page encryption mask from the Mmio region.

The series is based on the commit:
 15ee7b76891a CryptoPkg/BaseCryptLib: Fix possible uninitialized use
