    compositor-drm: prefer PCI boot_vga GPU over other GPUs

    If we can find a boot_vga PCI GPU, we should prefer it over any other GPU
    that is connected to the system. The boot_vga flag tells us that this GPU
    is the primary system GPU.

    This fixes problems on two-GPU-systems were the wrong GPU is used. It also
    fixes systems were DisplayLink GPUs are available with lower IDs than PCI
    GPUs (although, this seems unlikely).

    Note that udev_enumerate guarantees that the entry-list is sorted. So for
    systems that have platform-GPUs, these should almost always be reported
    prior to hotpluggable (PCI, USB, ...) GPUs, as the kernel probes them
    first.
