drm: Add acquire ctx to ->gamma_set hook
Atomic helpers really want this instead of the hacked-up legacy backoff trick, which unfortunately prevents drivers from using their own private drm_modeset_locks. Aside: There's a few atomic drivers (nv50, vc4, soon vmwgfx) which don't yet use the new atomic color mgmt/gamma table stuff. Would be nice if they could switch over and just hook up drm_atomic_helper_legacy_gamma_set() instead.
