[PATCH]: rpaphp: find_bus() -- remove duplicate code

[linas]

John Rose,
Please review and sign off, and forward to Greg KH!

--linas

The function rpaphp_find_pci_bus() has been migrated to 
pcibios_find_pci_bus() in arch/powerpc/platforms/pseries/pci_dlpar.c  
This patch removes the old version.
