The "get board rev" firmware API doesn't seem to return a useful value on
this platform, so we hard-code the board ID for now, since there's only
one bcm2836-based RPi board at present.
USB doesn't seem to work yet; the controller detects the on-board Hub/
Ethernet device but can't read the descriptors from it. I haven't
investigated yet.
HDMI is untested.
