fbdev: Remove conflicting devices on PCI bus

Remove firmware devices on the PCI bus, by calling
aperture_remove_conflicting_pci_devices() in the probe function of
each related fbdev driver. iSo far, most of these drivers did not
remove conflicting VESA or EFI devices, or outride failed for
resource conflicts (i.e., matroxfb.) This must have been broken
for quite some time.
