xf86drm: Drop drmFauxDeviceInfo

Browse source 
Its contents is the same as drmFauxBusInfo. While it is technically an
API breaking change, libdrm with the relevant changes has been released
only recently and there are issues with quering DRM nodes that are on
the faux bus, which result in crashes, so it is unlikely that there are
users that depend on the new API.
