The get_arch_dma_ops() arch-specific function never does anything with
the struct bus_type that is passed into it, so remove it entirely as it
is not needed.

Note: Unless someone objects, I would like to take this through the
driver-core tree, as further bus_type cleanups depend on it, and it's
stand-alone from everyone else's tree at the moment from what I can
determine.
