The new format specifier is '%pp', and prints a pci_sbdf_t using the
seg:bus:dev.func format. Replace all SBDFs printed using
'%04x:%02x:%02x.%u' to use the new format specifier.
No functional change intended.
Signed-off-by: Roger Pau Monné <roger.pau@citrix.com>

Changes since v1:
- Use base 8 to print the function number.
- Sort the addition in the pointer function alphabetically.

Ping? Since I've got an Ack from Jan and Julien I think the missing Acks are for the Intel stuff and x86 generic and AMD by Andrew, since Jan explicitly expressed his Ack is only for pieces where he is the only maintainer.
