[ARM PATCH] 1215/1: Vector relocation not being disabled at reset

This patch solves the problem of soft reboots on Iq80310, IQ80321, and BRH
platforms.  The problem was that during the RedBoot PCI scan, we were getting
data aborts due to non-existent PCI devices.  It looks like redboot doesn't
cleanup after us and turn of vector relocation, so we were jumping off into
nowhere.
