drm/amd/display: Remove conditional for shaper 3DLUT power-on
[ Upstream commit 1b38a87b8f8020e8ef4563e7752a64182b5a39b9 ]
[Why]
Shaper programming has high chance to fail on first time after
power-on or reboot. This can be verified by running IGT's kms_colorop.
[How]
Always power on the shaper and 3DLUT before programming by
removing the debug flag of low power mode.
