Almost everyone implements dma_set_mask the same way, although some time that's hidden in ->set_dma_mask methods. This patch consolidates those into a common implementation that either calls ->set_dma_mask if present or otherwise uses the default implementation. Some architectures used to only call ->set_dma_mask after the initial checks, and those instance have been fixed to do the full work. h8300 implemented dma_set_mask bogusly as a no-ops and has been fixed. Unfortunately some architectures overload unrelated semantics like changing the dma_ops into it so we still need to allow for an architecture override for now.
