.. and I've just fixed a locking bug, and I've introduced a new iicbb
hint which overrides udelay.

Next is adding some more twiddles to enable/disable iicbb debugging,
iicbus debugging and log transaction failures, ACK times, etc. The
read transactions all seem to fail ACK btw, so I wonder if that's the
majority of the CPU time being wasted..
