In this version, a template for the Algorithm class is introduced in patch 6/11 and 7/11 for the RkISP1 implementation. Now that AGC is working pretty nicely on IPU3, make it work on RkISP1 too. For that purpose, patches 1/11 to 5/11 reuse the concepts of Algorithm and IPAContext and make those part of the rkisp1 IPA. The effective sensor controls can then be reported with patch 8/11. Patch 9/11 is a small adaptation of the IPU3 AGC: we reuse the relative luminance estimation, basing it on the Y mean measured by the ISP, and removes the histogram based calculation for now. In v2 the improvements from Laurent's series "ipa: ipu3: agc: Misc improvements" are also included. Patch 10/11 introduces a new prepare() call from the Algorithm class in AGC, and patch 11/11 is making it revision independant.
