The exposure times in the exposure modes were causing AGC oscillations
because the algorithm was demanding long unachievable exposure times
but, without working sensor metadata, thought it was getting them when
actually it was not. We fix it by making the exposure profile request
only achievable exposure times, as we do for the ov5647 tuning.
