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.
Add three functions to drm_color_mgmt.c:
drm_crtc_supports_legacy_gamma() which tells if the driver supports
setting the legacy gamma.
drm_crtc_gamma_ramp_set() which sets the given gamma ramp to GAMMA_LUT
and resets DEGAMMA_LUT and CTM.
drm_crtc_legacy_gamma_set() which sets the given gamma ramp values
either using drm_crtc_funcs.gamma_set or drm_crtc_gamma_ramp_set().
These functions are used from the drm_mode_gamma_set_ioctl, and from
drm_fb_helper.c when it is dealing with fbdev cmap.
We can then drop drm_atomic_helper_legacy_gamma_set() and remove all its
uses.
Note that we need to EXPORT_SYMBOL all the new functions as they are
used from drm_fb_helper, but they are declared in drm_crtc_internal.h as
they are not supposed to be used by the drivers.
