[PATCH v4 0/3] OvmfPkg: mark flash memory range as MMIO

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

The Qemu flash range is marked as 'system ram' in EFI runtime memmap
but it is actually an IO address. The patch series updates the
EFI runtime memmap to add this range as Memory Mapped IO address.

Changes since v3:
- minor changes to address Laszlo's review feedback.

Changes since v2:
 - added cover letter and extend CC list to add all OvmfPkg
   maintainers/reviewers.

Changes since v1:
 - split the OvmfPkg single patch into three patches based on Laszlo's feedback.
  a) mark memory as MMIO for non SEV case
  b) do not adding EFI runtime mapping for SMM build
  c) clear C-bit when SEV is active for non SMM builds only
