mailbox: add tx_prepare client callback
If the mailbox controller expects the payload is in place before initiating the transmit, then it's impossible to reuse the list maintained by core mailbox code currently. Maintaining another list for sending the message in the controller seems totally unnecessary as core mailbox library already provides that feature. This patch introduces tx_prepare callback in mbox_client which can be used by the core mailbox library before initiating the transaction through mbox->ops->send_data. The client driver can implement this callback to ensure the payload is copied to the shared memory.
