merge a100u2w source files

From: 	Christoph Hellwig <hch@lst.de>

looking at the a100u2w driver the split between the inia100.c and
i60uscsi.c source files is hindering work badly.  So I'm attaching
below a new a100u2w.c that is a merge of those two, but no code changes
at all (yet) - just the comment headers and includes of the two merged,
then rest of i60uscsi.c, then rest of inia100.c.
