(5/6) bcm57xx: bcm4785 incomplete reboot
I noticed my wrt350n would not reliably reboot after entering the reboot command. I found this code in the source for the wrt600n. It corrects the problem, and the wrt350n reboots reliably now. Signed-off-by: Ben Pfountz <netprince (at) vt (dot) edu> SVN-Revision: 11470
