Bug description:
[Impact]
TTY switching is not possible on some workstations when iGPU is present and
NVIDIA GFX is boot VGA. On that case, fbdev /dev/fb* is not created.
[Fix]
Find the correct boot VGA and remove overlapped aperture (BAR), so fbdev can
be created properly.
[Test]
Once the fix gets applied, /dev/fb0 is present and TTY switching works.
[Where problems could occur]
The fix is a major overhaul over resource management on video apertures
(BAR), so the boot VGA discovery might change and different aperture might be
evicted.
