Subject: drm/tegra: vic: Track interface version
Git-commit: acae8a9d054daa75a01e34b18f3627e6df330622
Patch-mainline: v4.18-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Set the interface version implemented by the VIC module. This allows
userspace to pass the correct command stream when programming the VIC
module.
