ASoC: SOF: Add helper function to prepare and send an IPC message

Browse source 
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.
