Vincent Palatin 6473343075 better unhandled exception panic without runtime ...

On panic, reboot properly the CPU rather than just jumping to the reset
vector as that might lead to some incorrect initializations.

Properly plug the div by 0 to the panic handling.

Add a small trace if the debug output is activated.

BUG=chrome-os-partner:29840
TEST=add adhoc code triggering a data abort and see the firmware
printing a trace, then rebooting immediatly in a working state.
