PCI: quirks: Fix backport of quirk_io()

Commit 06cf35f903aa ('PCI: Handle read-only BARs on AMD CS553x
devices') added the function quirk_io() which calls
pcibios_bus_to_resource().

Prior to Linux 3.14, pcibios_bus_to_resource() takes a pointer to
struct pci_dev and looks up the device's bus itself, so we need
to pass dev not dev->bus.
