scripts: nrfjprog.py: Add --softreset switch

Browse source 
The current script relies on a hardware reset pin to release the chip
from reset. Software reset is also possible and even required in case
the reset pin hasn't been wired to the J-Link connector on the board.

This patch adds an additional command line switch to nrfjprog.py that
uses the software reset mechanism of nrfjprog instead of pin reset.
