When updating the Lighthouse deck as part of the flashing procedure we sometiems get stuck. The Lighthouse deck does not power on. We suspect this is connected to the capacitors on the deck not getting enough time to discharge in some conditions on some boards. Some users tried out firmware with 250 ms and 300 ms delays and the 300 ms delay fixed the issue for them. We increase the delay here to 350 ms to err on side of caution. If boot-up times becomes an issue we could change this to only take effect on soft-resets. Fixes: bitcraze#56

It seems like we need a delay when soft-reset during flashing to account for capacitators discharging causing signal troubles for the FPGA.
