From: Christoph Hellwig <hch@lst.de>
Subject: dma-mapping: consolidate dma_set_mask
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.
