The new sof_ipc_send_msg() can be used by IPC dependent code to prepare the ipc->msg for a new message transmission and then call in to platform code to send the message.

Higher level code should be handling the completion and reply.

Add the implementation for the IPC3 tx_msg callback for sending a single IPC message.

The implementation is equivalent to the currently used code in ipc.c

From: Peter Ujfalusi peter.ujfalusi@linux.intel.com

Add the implementation for the set_get_data callback for handling large data set and get.

The set_get_data() in IPC3 can be used only for component messages. The function expects the caller to prepare the message behind the data pointer for sending/receiving data. The callback only implements the needed code to be able to split up a message if needed for transfer.

The set_get_data ops is based on the existing snd_sof_ipc_set_get_comp_data() and sof_set_get_large_ctrl_data() but made it generic entry point.
