[ARM] 3063/1: allow slave ixp2000 cpu reset
Patch from Lennert Buytenhek On the ixdp2x00, the slave CPU is currently not allowed to reset itself for fear that it will do something 'funky' on the PCI bus. This fear is ungrounded -- the slave CPU is wired up such that a CPU reset will not cause a PCI bus reset to be done. This patch changes arch_reset() so that the slave CPU also executes the reset sequence, allowing it to reboot itself using /sbin/reboot.
