drm: automatic legacy gamma support
To support legacy gamma ioctls the drivers need to set drm_crtc_funcs.gamma_set either to a custom implementation or to drm_atomic_helper_legacy_gamma_set. Most of the atomic drivers do the latter. We can simplify this by making the core handle it automatically. Move the drm_atomic_helper_legacy_gamma_set() functionality into drm_color_mgmt.c to make drm_mode_gamma_set_ioctl() use drm_crtc_funcs.gamma_set if set or GAMMA_LUT property if not.
