drm/amd/display: Disable dsc_power_gate for dcn314 by default
[ Upstream commit 02f3ec53177243d32ee8b6f8ba99136d7887ee3a ]
[Why]
"REG_WAIT timeout 1us * 1000 tries - dcn314_dsc_pg_control line"
warnings seen after resuming from s2idle.
DCN314 has issues with DSC power gating that cause REG_WAIT timeouts
when attempting to power down DSC blocks.
[How]
Disable dsc_power_gate for dcn314 by default.
