ACPI: pci_slot.ko wants a 64-bit _SUN

Similar to commit b6adc195 (PCI hotplug: acpiphp wants a 64-bit
_SUN), pci_slot.ko reads and creates sysfs directories based on
the _SUN method.

Certain HP platforms return 64 bits in _SUN. This change to
pci_slot.ko allows us to see the correct sysfs directories.
