ipa: rkisp1: Introduce AGC
Now that we have IPAContext and Algorithm, we can implement a simple AGC based on the IPU3 one. It is very similar, except that there is no histogram used for an inter quantile mean. The RkISP1 is returning a 5x5 array (for V10) of luminance means. Estimating the relative luminance is thus a simple mean of all the blocks already calculated by the ISP.
