[POWERPC] bootwrapper: Add PowerQUICC II (82xx with CPM) cuboot support

Browse Source 
This allows booting on legacy, non-device-tree aware versions of U-boot.

It also fixes up the hardware to match the PCI and chipselect information
in the device tree, as u-boot is inconsistent in setting these up
correctly (or at all).
