Hi Tony,
the following two patches get rid of
the static global variable holding the
bus context. It's not needed at all.
This will allow us to have multiple
CBUS buses by using different GPIOs.
Will never be useful, but that's it
should've been done anyway :-p

Hmm the second patch "cbus: pass device as argument" breaks booting on n800. Anyways pushed out already so that will need to be fixed in a separate patch.
