[POWERPC] 4xx: Fix PESDRn_UTLSET1 register setup on 460EX/GT
The patch fixes a bug, where the PESDRn_UTLSET1 register was setup wrongly resulting in a non working PCIe port 1. With this fix both PCIe ports work fine again. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
