xfree86: Make adding unclaimed devices as GPU devices a separate step

Browse Source 
This is primarily a preparation patch for fixing the xserver exiting with
a "no screens found" error even though there are supported video cards,
due to the server not recognizing any card as the primary card.

This also fixes the (mostly theoretical) case of a platformBus capable
driver adding a device as GPUscreen before a driver which only supports
the old PCI probe method gets a chance to claim it as a normal screen.
