[PATCH] powerpc/pasemi: Seach for PCI root bus by compatible property

[Darren Stevens]

Pasemi arch code finds the root of the PCI-e bus by searching the
device-tree for a node called 'pxp'. But the root bus has a 
compatible property of 'pasemi,rootbus' so search for that instead.

This works on the Amigaone X1000, I don't know if this method of
finding the pci bus was there bcause of earlier firmwares.
