powerpc/mpc85xx: Make Freescale PCI bridge driver a subclass of ofw_pcib_pci

This driver was already 99% identical to the ofw_pcib_pci driver, except for
the attachment. Since ofw_pcib_pci is already a subclass of pcib, this
creates a private declaration of that class, to use for the base class for
this driver.

At some point in the future, ofw_pcib_pci_driver should probably be exported
to a header, so we're not tracking the softc struct contents, but for now,
since there's only this one other driver, it's not a pressing issue.

Expand the Freescale PCIe root complex driver with the ofw_pcib_pci

The interrupt map wasn't being allocated properly, preventing IRQs from being
allocated to children of the PCIe bus. Fix this by cloning the ofw_pcib_pci
code, which handles all cases -- device tree and probed.

In the future this may become a subclass of the ofw_pcib_pci driver, but as
that's not an exported class, it's cloned for now.

Modernize mpc85xx PCI hostbridge driver.

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.

Add a PCI bridge for the Freescale PCIe Root Complex

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.

Add a PCI bridge for the Freescale PCIe Root Complex

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.
