This patch contains a set of uncontroversial changes to PCI sysfs.

 - Always output 64-bit resources so userspace doesn't need ifdefs
   and 32-bit userspace works on 64-bit architectures.  Separate them
   with spaces rather than tabs.
 - Prefix hex quantities with "0x"
 - Always show 7 resources for non-bridge devices, and all resources for
   bridges rather than stopping on the first empty resource.
