Subject: drm/amd/display: Add headers for hardcoded 1d luts.
Git-commit: 8d2bbe54d18906e456c1ba0e1b0aa9fd175cae97
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Hard-coded luts are needed since complex algorithms are used for
color and tone mapping. Add the headers for future use.
