ipa: rkisp1: agc: Don't update histogram parameters unnecessarily
The ISP histogram parameters depends on the AE metering mode, but not on the other AE algorithm controls. The exposure mode, constraints mode and frame duration limits influence the behaviour of the algorithm, but not the histogram computation parameters. Update the histogram parameters only when AE metering mode changes.
