This is MT8173 gamma & dither support PATCH v2, based on 4.7-rc1.
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.
