xfree86: don't enable anything in xf86InitialConfiguration for GPU screens 

There's no point in turning on outputs connected to GPU screens during initial
configuration.  Not only does this cause them to just display black, it also
confuses clients when these screens are attached to a master screen and RandR
reports that the outputs are already on.

Also, don't print the warning about no outputs being found on GPU screens,
since that's expected.
