drm/mediatek: Add mtk_dither_set_common() function
Current implementation of mtk_dither_set() cast dev data to struct mtk_ddp_comp_dev. But other devices with different dev data would also call this function. Separate necessary parameters out so other device components (dither, gamma) can call this function.
