Log Message:
pci: Pass cookie through pci_find_device, pci_enumerate_bus, take 2.

New functions pci_find_device1 and pci_enumerate_bus1 have the cookie
argument.  Existing symbols pci_find_device and pci_enumerate_bus are
now wrappers for the cookieless version.

This will allow pci_find_device callers to pass a cookie through to
the match function so they can keep state or pass in extra parameters
like b/d/f numbers, which will allow us to nix some horrible kludges
in the Linux PCI API emulation for drm (and, perhaps, Intel wifi).

This change drops the symbol pci_probe_device, in favour of a new
pci_probe_device1 with the cookie argument.  But I don't think that
requires a revbump because it's only called by MD pci_enumerate_bus1
implementations, which don't live in modules anyway.

Take 2: Make sure to handle NULL match function.
