PCI: fix pci_fixup_video as it blows up on sparc64

This reverts much of the original pci_fixup_video change and makes it
work for all arches that need it.

fixed, and tested on x86, x86_64 and IA64 dig.

- * Fixup to mark boot BIOS video selected by BIOS before it changes
- *
- * From information provided by "Jon Smirl" <jonsmirl@gmail.com>
- *
- * The standard boot ROM sequence for an x86 machine uses the BIOS
- * to select an initial video card for boot display. This boot video
- * card will have it's BIOS copied to C0000 in system RAM.
- * IORESOURCE_ROM_SHADOW is used to associate the boot video
- * card with this copy. On laptops this copy has to be used since
- * the main ROM may be compressed or combined with another image.
- * See pci_map_rom() for use of this flag. IORESOURCE_ROM_SHADOW
- * is marked here since the boot video device will be the only enabled
- * video device at this point.
