PCI: Include PCI domain in PCI bus names on x86/x86_64
The PCI bus names included in /proc/iomem and /proc/ioports are of the form 'PCI Bus #XX' where XX is the bus number. This patch changes the naming to 'PCI Bus XXXX:YY' where XXXX is the domain number and YY is the bus number. For example, PCI bus 14 in domain 0 will show as 'PCI Bus 0000:14' instead of 'PCI Bus #14'. This change makes the naming consistent with other architectures such as ia64 where multiple PCI domain support has been around longer.
