This is MT8173 gamma & dither support PATCH v4, based on 4.7-rc1. Changes since v3: -Split the GAMMA patch into 3 patches. --AAL engine basic function --GAMMA engine basic function --GAMMA correction config function -Align the all definition to 4 digits. -Remove HW constrain check from calculate bpc. -Use symbol to replace magic number. -Add a function "mtk_dither_set". Changes since v2: -Modify defines to match the register field names in the MT8173 datasheet -Made dithering function support hardware mirroring well on two monitor. Changes since v1: -According to the suggestion from Daniel, we used the new atomic color management. -Applied gamma function at GAMMA engine (path 2). -Made dithering function support hardware mirroring well. -Removed the bpc variable from mtk_drm_crtc struct.
