FP2: Fix underexposed OV5670 image sensor output
Previews, captured images and videos can turn out underexposed with the
OV5670 image sensor. This underexposure is caused by the capture frame
rate running at a fixed 30 frames per second. Instead the auto-exposure
routine can take a range, over which it can adjust the capture frame
rate to maintain good exposure.
Fix the issue by setting a target FPS range for the Fairphone 2 front
camera for all image captures, ranging from 7 to 30 FPS.
Issue: FP2P-587
