[RFC PATCH 19/40] drm/amd/display: update lut3d and shaper lut to stream

[Melissa Wen]

It follows the same path of out_transfer_func for stream updates, since
shaper LUT and 3D LUT is programmed in funcs.set_output_transfer_func()
and this function is called in the atomic commit_tail when
update_flags.bits.out_tf is set.
