#1187401 — [PATCH v7 1/3] dt/bindings: Add binding for the Raspberry Pi firmware driver

This driver will provide support for calls into the firmware that will
be used by other drivers like cpufreq and vc4.

v2: Improve commit message, point to mailbox.txt for how mboxes work.
v3: Use Lee's suggestion for mailbox phandle docs, fix spelling of
    "raspberry".
v4: Change the compatible string to "raspberrypi,bcm2835-firmware"
    (requested by Lee, agreed by Stephen)
v5: Add missing s-o-b, fix spelling.

v2: Drop pm-domains stuff since I've dropped it from the firmware
