Subject: drm/amd/display: Drop unnecessary detect link code
Git-commit: ec457f8378901d673b841e81d289b0165286db7f
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
Delete unnecessary codes in detect_link_and_local_sink. We already have
correct stop logic in dc_link_detect.
