Yoichi Yuasa fd6e732186 PCI: fix IDE legacy mode resources
I got the following error on MIPS Cobalt.

PCI: Unable to reserve I/O region #1:8@f00001f0 for device 0000:00:09.1
pata_via 0000:00:09.1: failed to request/iomap BARs for port 0 (errno=-16)
PCI: Unable to reserve I/O region #3:8@f0000170 for device 0000:00:09.1
pata_via 0000:00:09.1: failed to request/iomap BARs for port 1 (errno=-16)
pata_via 0000:00:09.1: no available native port

The legacy mode IDE resources set the following order.

pci_setup_device()
    Legacy mode ATA controllers have fixed addresses.
    IDE resources: 0x1F0-0x1F7, 0x3F6, 0x170-0x177, 0x376
    |
    V
pcibios_fixup_bus()
    MIPS Cobalt PCI bus regions have the -0x10000000 offset from PCI resources.
    pcibios_fixup_bus() fix PCI bus regions.
    0x1F0 - 0x10000000 = 0xF00001F0

    V
ata_pci_init_one()
    PCI: Unable to reserve I/O region #1:8@f00001f0 for device 0000:00:09.1

In some architectures, PCI bus regions have the offset from PCI resources. 
For this reason, pci_setup_device() should set PCI bus regions to
dev->resource[].
