OvmfPkg/QemuFlashFvbServicesRuntimeDxe: mark Flash memory range as MMIO
The flash memory range is an IO address and should be presented as Memory
Mapped IO in EFI Runtime mapping. This information can be used by OS
when mapping the flash memory range.
It is especially helpful in SEV guest case, in which IO addresses should
be mapped as unencrypted. If memory region is not marked as MMIO then OS
maps the range as encrypted.
