[PATCH 08/10] dt/bindings: Add binding for BCM2835 mailbox property channel driver

I was tempted to have the mailbox property channel support just be in
the 2835 mailbox driver itself, but mbox_request_channel() wants its
device to have the "mboxes" node, and that appears to be only intended
for mailbox clients, not controllers.
