Anup Patel ac75c29c9c mailbox: Allow controller specific mapping using fwnode ...

[ Upstream commit ba879dfc05 ]

Introduce optional fw_node() callback which allows a mailbox controller
driver to provide controller specific mapping using fwnode.

The Linux OF framework already implements fwnode operations for the
Linux DD framework so the fw_xlate() callback works fine with device
tree as well.
