Kun Qin 93ee300675 ArmPkg: StandaloneMmCoreEntryPoint: Use ARM_FFA_ARGS for misc buffer
The MISC_MM_COMMUNICATE_BUFFER stored the FF-A direct message
registers in a DIRECT_MSG_ARGS structure. Populating and reading it
required manually re-indexing every register (EventSvcArgs->Arg4..Arg17
into DirectMsgArgs.Arg0..Arg13). This shifted the register positions and
left the buffer layout inconsistent with the raw FF-A argument register
file, making it error prone to correlate a slot with its architectural
register.
