This patchset adds a gamma algorithm and the corresponding control for rkisp1.
A camera gamma of roughly 2.2 is necessary to produce correct output images on
a standard monitor and to comply with sRGB.

v1 -> v2:
- fixed some stylistic issues from review
- added gamma control only if algorithm is present
