[PATCHv3 06/14] mailbox: create opened message type

From: Loic Pallardy Current message type is a u32 to fit HW fifo format. This should be extended to support any message exchanges and type of mailbox. Proposed structure owns the original u32 and an optional pointer on additional data. Adaptations made to remoteproc and tidspbridge drivers.
