ipa: rkisp1: algorithms: agc: Check for correct stats type
Sometimes the ISP produces statistics only with a subset of statistic
types being valid. It doesn't happen normally, but was observed in the
wild. Check for the RKISP1_CIF_ISP_STAT_AUTOEXP bit to prevent using
invalid or outdated data. As it doesn't happen regularly add an error
message to get notified when it happens.
