David Plowman	42562d6d33	ipa: rpi: agc: Change handling of colour gains less than 1 ... Previously these were handled in the AGC/AEC exposure update calculations by explicitly driving a higher digital gain to "cancel out" any colour gains that were less than 1. Now we're ignoring this in the AGC and leaving it to the IPA code to normalise all the gains so that the smallest is 1. We don't regard this as a "real" increase because one of the colour channels (just not necessarily the green one) still gets the minimum gain possible. We do, however, update the statistics calculations so that they reflect any such digital gain increase, so that images are driven to the correct level.
