[PATCH 2/2] drm/amd/display: Fix incorrect power gating configuration for DOMAIN11

The current implementation incorrectly updates DOMAIN11_PG_CONFIG with
DOMAIN9_POWER_FORCEON, which is not the intended behavior. This patch
corrects the power gating configuration by updating DOMAIN11_PG_CONFIG
with DOMAIN11_POWER_FORCEON, preventing potential issues related to
power management.

Fixes: 46825fcfbe16 ("drm/amd/display: avoid power gate domains that doesn't exist")
