Subject: [PATCH] ppc64: uniform usage of bus unit id interfaces

01-pci-dn-uniformization.patch

This patch changes the rtas_pci interface to use the new struct pci_dn
structure for two routines that work with pci device nodes.

This patch also does some minor janitorial work: it uses some handy macros
and cleans up some trailing whitespace in the affected file.
