[POWERPC] Removed dead code related to PCI on ppc32
There are no in kernel users of any off these functions and some of them were not even EXPORT_SYMBOL: - pci_bus_io_base() - pci_bus_io_base_phys() - pci_bus_mem_base_phys() - pci_resource_to_bus() - phys_to_bus() - pci_phys_to_bus() - pci_bus_to_phys() - pci_init_resource() - resource_fixup() Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
