[POWERPC] Remove hack to determine the 2nd PHBs bus number
Now that we have the pci_controller in the exclude function we can easy figure out if the bus number is the PHB or not. The old style of using a variable setup at init time was actually broken and would only work in specific cases. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
