Should we start thinking about routing bcm2835/36 changes through the
same Broadcom pull request as we do for the every other SoCs within
mach-bcm: 63xx, 53xx/47xx, brcmstb, cygnus at some point?

I don't have any strong feelings either way, just curious if this is
something remotely desireable from an arm-soc maintainer role perspective.
