Meelis reported that qla2000 driver does not get loaded on one sparc system.
schizo f00732d0: PCI host bridge to bus 0001:00
pci_bus 0001:00: root bus resource [io 0x7fe01000000-0x7fe01ffffff] (bus address [0x0000-0xffffff])
pci 0001:00:06.0: quirk: [io 0x7fe01000800-0x7fe0100083f] claimed by ali7101 ACPI
pci 0001:00:06.0: quirk: [io 0x7fe01000600-0x7fe0100061f] claimed by ali7101 SMB
pci 0001:00:07.0: can't claim BAR 0 [io 0x7fe01000000-0x7fe0100ffff]: address conflict with 0001:00:06.0 [io 0x7fe01000600-0x7fe0100061f]
So the quirk for M7101 claim the io range early.
According to spec with M7101 in M1543 page 103/104,
http://www.versalogic.com/Support/Downloads/pdf/ali1543.pdf
0xe0, and 0xe2 do not include address info for acpi/smb.
Kill wrong quirk about them.
