[patch 1/3] PCI: print quirk name in debug messages

[bjorn.helgaas@hp.com]

Instead of printing this:

    PCI: Calling quirk c023b250 for 0000:00:00.0

we can print this:

    pci 0000:00:00.0: calling quirk 0xc023b270: quirk_cardbus_legacy+0x0/0x30()

The address is superfluous because sprint_symbol() includes the
address if the symbol lookup fails, but this is the same style used
in do_initcalls() and pnp_fixup_device().
