Mailbox: Generic: Specify mailbox api bindings
Due to the platform specific nature of remote's firmware, we can't do much
to facilitate shareable client drivers. So the Mailbox api is more like a
bunch of useful functions put together. The only feature that can be
abstracted out is mailbox channel assignment to client drivers, which this
binding specifies.
