[IA64] add the MMIO regions that are translated to I/O port space to /proc/iomem
ia64 translates normal loads and stores to special MMIO regions into I/O port
accesses. Reserve these special MMIO regions in /proc/iomem.
Sample /proc/iomem:
f8100000000-f81003fffff : PCI Bus 0000:80 I/O Ports 00000000-00000fff
f8100400000-f81007fffff : PCI Bus 0000:8e I/O Ports 00001000-00001fff
f8100800000-f8100ffffff : PCI Bus 0000:9c I/O Ports 00002000-00003fff
f8101000000-f81017fffff : PCI Bus 0000:aa I/O Ports 00004000-00005fff
and corresponding /proc/ioports:
00000000-00000fff : PCI Bus 0000:80
00001000-00001fff : PCI Bus 0000:8e
00002000-00003fff : PCI Bus 0000:9c
00004000-00005fff : PCI Bus 0000:aa
