[media] ov2640: add information about DSP register 0xc7
According to ov2640 software application notes, there are two Automatic
White Balance (AWB) modes, which are selected by DSP register 0xc7:
1) Simple AWB: assumes the average color is gray
+ independent from lens
- doesn't work well if captured area contains unbalanced colors
(e.g. large blue background)
2) Advanced AWB: uses color temperature information
+ more accurate, works with all image contents
- lens specific, requires calibration
