nb/intel/sandybridge/acpi: Support setting PCI bars above 4G

Although coreboot can allocate resources above 4G, Linux does not
consider those allocation valid when there is no region above 4G in
_CRS and disables the device.

TESTED: x220 with and external GPU via the expresscard slot. Linux
does not touch the BARs allocated above 4G.
