media: rockchip: rkisp1: extend uapi array sizes

Later variants of the rkisp1 block use more entries in some arrays: RKISP1_CIF_ISP_AE_MEAN_MAX 25 -> 81 RKISP1_CIF_ISP_HIST_BIN_N_MAX 16 -> 32 RKISP1_CIF_ISP_GAMMA_OUT_MAX_SAMPLES 17 -> 34 RKISP1_CIF_ISP_HISTOGRAM_WEIGHT_GRIDS_SIZE 25 -> 81 and we can still extend the uapi during the 5.11-rc cycle, so do that now to be on the safe side. V10 and V11 only need the smaller sizes, while V12 and V13 needed the larger sizes. When adding the bigger sizes make sure, values filled from hardware values and transmitted to userspace don't leak kernel data by zeroing them beforehand.
