Subject: drm/tegra: vic: Use autosuspend
Git-commit: b03d6403072edae18a7eb5359eaf8e7efd3d2bb9
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
When going idle, it's not unlikely that more work will follow.
As such, use autosuspend with a 500ms suspend delay.
