	When a new parameter buffer needs to be queued, we need to specify which algorithm is activated or not in the ISP. Add a simple prepare function in AGC for that, which may later evolve to take the exposure locking into account. For that function to be called, we also need to add the loop on the algorithms in IPARkISP1::queueRequest. We no longer disable the AE algorithm based on the controls::AeEnable, which will be handled in a different manner later.

2021-11-29	ipa: rkisp1: Introduce AGC	Jean-Michel Hautbois
	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.
