From: Marcel Apfelbaum <address@hidden>
PXBs do not support hotplug so they don't have a PCNT function.
Since the PXB's PCI root-bus is a child bus of bus 0, the
build_dsdt code will add a call to the corresponding PCNT function.
Fix this by skipping the PCNT call for the above case.
While at it skip also PCIe child buses.
