Subject: drm/vc4: hdmi: Remove drm_encoder->crtc usage
Git-commit: 27da370e0fb343a0baf308f503bb3e5dcdfe3362
Patch-mainline: v5.15-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
The drm_encoder crtc pointer isn't really fit for an atomic driver,
let's rely on the connector state instead.
