scripts: linksys-image: add NAND devices

The larger switches of the Linksys LGS series (e.g. LGS352C) make
use of NAND. So the vendor firmware uses other commands to upload
an image through the WebUI.

Add the required scripts. With this we can upload an image to all
devices of that series. Independant of NOR or NAND.
