check if the device ID in the form of pci match, while
for firmware interfaces we require the pci ID to
match. It's assumed that platform interfaces always match,
since we can't actually associate them with IDs.
A further awkwardness is that, while it's theoretically
possible for an ACPI interface to include support for
changing the backlight of external devices, it's unlikely
to ever be done. It's effectively impossible for a platform
interface to do so. So if we get asked about anything that
isn't LVDS or eDP, we pretty much have to require that the
