drm/radeon: Bypass hw lut's for > 8 bpc framebuffer scanout. The hardware lut's only have 256 slots for indexing by a 8 bpc framebuffer. In 10 bpc scanout modes, framebuffer color values would get truncated to their 8 msb's, thereby losing the extra precision afforded by a 10 bpc framebuffer. To retain full precision, bypass the hw lut in 10 bpc scanout mode. Signed-off-by: Mario Kleiner <mario.kleiner.de@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
