Well, 'pci_devs_phb_init_dynamic', 'scan_phb' & 'pci_bus_add_devices'
has been defined at ./arch/powerpc/include/asm/ppc-pci.h, but as
	#ifdef CONFIG_PCI
the reason for which the declarations were not visible. And these
would churn out few additional failures also for PPC build, like:

The following patch attempts to fix them all. I had tested them. Please review.
