Log:
bcm2835_vcbus: add legacy compat mappings
I've opted for just duplicating the two entries needed for this, rather than
writing any other mechanism for maintaining two root compat entries to map
to one config, for simplicity. We'll eventually declare these legacy DTB
unsupported, but let's not do that yet while there's no real burden.
