    drm: allow DRM_IOCTL_VERSION on render-nodes
    
    DRM_IOCTL_VERSION is a reliable way to get the driver-name and version
    information. It's not related to the interface-version (SET_VERSION ioctl)
    so we can safely enable it on render-nodes.
    
    Note that gbm uses udev-BUSID to load the correct mesa driver. However,
    the VERSION ioctl should be the more reliable way to do this (in case we
    add new DRM-bus drivers which have no BUSID or similar).
