[RFC/PATCH 5/10] powerpc: pci32: Remove obsolete PowerMac bus number hack
From: Benjamin Herrenschmidt <benh@kernel.crashing.org>

The 32 bits PCI code carries an old hack that was only useful for G5 machines. Nowdays, the 32 bits kernel doesn't support any of those machines anymore so the hack is basically never used, remove it.
