powerpc/pci: Export pci_traverse_device_nodes()
This renames traverse_pci_devices() to pci_traverse_device_nodes().
The function traverses all subordinate device nodes of the specified
one. Also, below cleanup applied to the function. No logical changes
introduced.
* Rename "pre" to "fn".
* Avoid assignment in if condition reported from checkpatch.pl.
