Revert "drm/amd/display: Remove unused cm3_helper_translate_curve_to_degamma_hw_format"

Browse source

This reverts commit 8b89acc0b2.

So that we can detach NL->L LUT programming from L->NL one, i.e., we can
use cm3_helper_translate_curve_to_degamma_hw_format for plane degamma and
blend (post-3DLUT curve) and cm3_helper_translate_curve_to_hw_format for
plane shaper (pre-3DLUT curve) and stream regamma.
