CBB now handles nightmode correctly (by deferring to Lua), so we no longer need to do monkey dances about disabling it when hw invert is missing. canUseCBB cap is resolved by generic device re-configuring blitbuffer on the go, so as to avoid repeating the same thing in every device driver. The dev setting can now flip cbb on the go, so one can gloat at the near meaningless perf difference - 2Mp draw is 15ms Lua / 10ms C on 1GHz Cortex A7.
