-----------
OvmfPkg/EmuVariableFvbRuntimeDxe: avoid accessing varstore header with cmp
Use explicit MmioReadXX() calls to enforce use of instructions supported
by #VC exception handler emulator. Does also work in case the varstore
header is located in RAM or ROM because x86 has no special mmio
instructions and non-x86 architectures do not use this code.
