Subject: drm/amd/display: Fix OPTC function pointers for DCN314
Git-commit: 2ce0b2186c057a54a4d980b296bd1659d0091716
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
[Why]
Access violation occurs when swapping between HDMI and FRL monitors
because we're missing the immediate_disable_crtc callback and it's
required for the DCN314 clk manager.
[How]
Update the table to match the DCN31 optc functions for ones that
should be the same:
- immediate_disable_crtc
- configure_crc
