proposed addition for sys/raid/ips (ServeRaid) driver in order to support latest 6M cards from Adaptec

[YONETANI Tomokazu]

Oops, a style fix to a comment in ips_commands.c accidentally slipped into
ips-new.diff.gz rather than ips-style.diff.gz, and another style fix
(removing unneccessary #include line) is backed out in ips-new.diff.gz .
Although this mistake does not affect resulting driver, I put revised
diffs at

in case the patches have chance to go into the tree.
