John Baldwin 4f9795b9fe Add a new method PCI_FIND_EXTCAP() to the pci bus interface that is used
to search for a specific extended capability.  If the specified capability
is found for the given device, then the function returns success and
optionally returns the offset of that capability.  If the capability is
not found, the function returns an error.
