s/nad/and/

Is it possible to rename bcm2835_audio to bcm2835-audio for consistency?
Or is that baked into existing usage/abi already?

If it can be changed, I think it's probably something to do in an
independent patch at the end of the series anyway.

I suspect this patch could be merged with 1/5 but I think it's ok
separate too.
