bcm2835_property: implement "get board revision" query

Browse source 
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.
