AMD/agesa: Add functions for AMD PCI IRQ routing

Port the changes that were made in amd/cimx to amd/agesa
as were done in:
   commit c93a75a5ab067f86104028b74d92fc54cb939cd5
   Author: Mike Loptien <mike.loptien@se-eng.com>
   Date:   Fri Jun 6 15:16:29 2014 -0600

      AMD/CIMx: Add functions for AMD PCI IRQ routing

This change also moves the PCI INT functions to
southbridge/amd so that they can be used by CIMX and
AGESA. The amd/persimmon board is updated for this
change.
