[PATCH 2/2] pci: Use new %pR to print resource ranges

From: Benjamin Herrenschmidt
Date: Mon Oct 20 2008 - 00:08:49 EST

This converts things in drivers/pci to use %pR to printout the
content of a struct resource instead of hand-casted %llx or
other variants.

I didn't go down the subdirs in there and I might have missed one
or two but the bulk is converted.
