nRF52840 MDK USB Dongle Espruino Port

Yep, It build quite fine for every Espruino board, and yes I always use make clean first. I think I found the problem, basically in the board file i was using the function:

def get_pins():

contained the pin array as

 pins = []

I changed it as i found in the nrf52840dk.py

pins = pinutils.generate_pins(0,47)

Now everything builds correctly but I'm not sure what I did is correct
