    xf86: Fix non-PCI configuration-less setups
    
    For non-PCI video devices, such as those found on many ARM embedded
    systems, the X server currently requires the BusID option to specify the
    full path to the DRM device's sysfs node in order to properly match it
    against the probed platform devices.
    
    In order to allow X to start up properly if either the BusID option was
    omitted or no configuration is present at all, the first video device is
    used by default.
