Altix: Initial ACPI support - ROM shadowing.
Support a shadowed ROM when running with an ACPI capable PROM.
Define a new dev.resource flag IORESOURCE_ROM_BIOS_COPY to
describe the case of a BIOS shadowed ROM, which can then
be used to avoid pci_map_rom() making an unneeded call to
pci_enable_rom().
