[PATCH 1/3 v3] dt/bindings: Add binding for the Raspberry Pi firmware driver

[Eric Anholt]

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".
