dfu: let the device reset itself
dfu flashing the ST12 was easy, but i was never able to get ST34 into dfu mode. Changing the firmware so it resets itself just like the octsim instead of starting a timer and waiting for a reset from the host made it work every time for me. Change-Id: Ida636ec925f40d6d56551f170150181350d03bbd
