devicetree: Discriminate device ops scan_bus()

Use of scan_static_bus() and tree traversals is somewhat convoluted.
    Start cleaning this up by assigning each path type with separate
    static scan_bus() function.

For ME, SMBus and LPC paths a bus cannot expose bridges, as those would
    add to the number of encountered PCI buses.
