src/sys/arch/sparc64/dev: pci_machdep.c
src/sys/arch/sparc64/include: pci_machdep.h
src/sys/arch/xen/include: pci_machdep.h

src/sys/dev/pci: pci.c pcivar.h
Log Message:
pci: Pass cookie through pci_find_device, pci_enumerate_bus.
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 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.
