[PATCH v2 0/4] SEV-ES TPM enablement fixes

["Lendacky, Thomas" <thomas.lendacky@amd.com>]

From: Tom Lendacky <thomas.lendacky@amd.com>

This patch series provides fixes for using TPM support with an SEV-ES
guest.

The fixes include:

- Decode ModRM byte for MOVZX and MOVSX opcodes.
- Add MMIO support for MOV opcodes 0xA0-0xA3.
- Create a new TPM MMIO ready PPI guid, gOvmfTpmMmioAccessiblePpiGuid
- Mark TPM MMIO range as un-encrypted during PEI phase for an SEV-ES
  guest and install the TPM MMIO ready PPI guid.
