Subject: drm: rcar-du: Shutdown the display on remove
Git-commit: 5e7ef0b85c7718c10f6122caf7af9b2e70d53830
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

When the device is unbound from the driver (the DU being a platform
device, this occurs either when removing the DU module, or when
unbinding the device manually through sysfs), the display may be active.
Make sure it gets shut down.
