It seems to me that it ought to be possible to avoid the need for all these
functions that just call i2c_bitbang_* by having the latter take a cookie
that includes a reference to the relevant bbops structure.  I suppose that
just replaces code indirection with data indirection, though, so it may not
be worth the effort.
