PCI subsystem: Use subordinate property to track bus enumeration

Parameter max is the cumulative number of PCI buses scanned on the
    system so far. Use the property subordinate from the parent PCI bridge
    device to keep track of the first available bus number instead of
    passing that on the stack.
