struct ipc_message contains fields: header, tx_data and tx_size which represent TX i.e. request while RX is represented by rx_data and rx_size with reply's header equivalent missing. Reply header may contain some vital information including, but not limited to, received payload size. Some IPCs have entire payload found within RX header instead. Content and value of said header is context dependent and may vary between firmware versions and target platform. Current model does not allow such IPCs to function at all. Rather than appending yet another parameter to an already long list of such for sst_ipc_tx_message_XXXs, declare message container in form of struct sst_ipc_message and add them to parent's ipc_message declaration. Align haswell, baytrail and skylake with updated request-reply model and modify their reply processing functions to save RX header within message container. Despite the range of changes, status quo is achieved.
