drm/amd/display: fix gamma not being applied correctly
[ Upstream commit 8ce504b9389be846bcdf512ed5be8f661b3bf097 ]
[why]
Gamma was always being set as identity on SDR monitor,
leading to no changes in gamma. This caused nightlight to
not apply correctly.
[how]
Added a default gamma structure to compare against
in the sdr case.
