ArmPkg: MmCommunicationDxe: MM communicate function argument attributes 

Current MM communicate2 function from ArmPkg described input arguments
`CommBufferPhysical`, `CommBufferVirtual` and `CommSize` as input only,
which mismatches with the "input and output type" as in PI specification.

This change updated function descriptions of MM communite2 to match input
argument types.
