bcm2835_property: implement "get board revision" querypull-target-arm-20160211
Return a valid value from the BCM2835 property mailbox query "get board revision". This query is used by U-Boot. Implementing it fixes the first obvious difference between qemu and real HW. The value returned is currently hard-coded to match the RPi2 I own. Other values are legal, e.g. different board manufacturer field values are likely to exist in the wild.
