There are mailbox clients that can discover the mailbox channel
identifiers at runtime. For such cases passing the channel
identifiers via DT is redundant.

The framework API will be supplied with mbox_request_channel_by_args().
It will allow clients to request a mailbox channel using the runtime
discovered channel identifiers.

Add support for referencing controllers solely by phandle.
