Subject: drm/omap: add plane_atomic_print_state support
Git-commit: 19e2d2669dacfd3783b6f948bf06a109a7cd668d
Patch-mainline: v5.17-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
Now that we added specific item to our subclassed drm_plane_state
we can add omap_plane_atomic_print_state() helper to dump out our own
driver specific plane state.
