Log Message:
-----------
MdeModulePkg: consider UNSUPPORTED return as valid in ArmFfaStandaloneMmLib
commit b534cabbdac4 ("ArmFfaLib: Add Rx/Tx support for Stmm secure partition")
makes ArmFfaStandlaoneMm(Core)Lib map Rx/Tx buffer in its constructor.
This makes a failure of loading StandaloneMm in legacy platform
which doesn't implements Rx/Tx buffer related API since it doesn't need to.
StandaloneMm could be only service provider not cosumer in some platform
where doesn't need to map RxTx buffer.
Therefore, Considier EFI_UNSUPPORTED return in ArmFfaStandaloneMmLib's
constructor.
