ipa: rkisp1: Introduce AWB
The RkISP1 ISP calculates a mean value for Y, Cr and Cb at each frame. There is a RGB mode which could theoretically give us the values for R, G and B directly, but it seems to be failing right now. Convert those values into R, G and B and estimate the gain to apply in a grey world.
