Summary:
* Take advantage of NEW_PCIB to remove a lot of setup code.
* Fix some bugs related to multiple PCI bridges.
There's still room for more cleanup, and still some bugs leftover, but this
cleans up a lot.
Test Plan: Tested on P5020 board with IDT PCIe switch.

Summary:
The Freescale PCIe Root Complex shows up as a Processor class device, PowerPC
subclass, so the generic PCI code ignores it for a bridge. This adds support
for it.
As part of this, update the Freescale PCI hostbridge driver, to allow probing
beyond the root complex, instead of only allowing "proper" PCI-PCI bridges.
