The latest specs say to use fixed timeouts, ignoring CSD values.
So the latest code (which I'll repost when git-mmc merges) got rid of
the bogus MINI timeout, and uses those timeouts unconditionally.
There seems to be no downside to using slightly longer timeouts than
a given older-spec card would tolerate.
