The WRT1900AC among other Linksys routers uses a dual-firmware layout.
The bootloader passes the active rootfs in bootargs and also sets the
rootfstype to jffs2 - which is clearly something we don't want.
Rename both root= and rootfstype= variables to avoid issues and also
use the former to dynamically rename the active partition to "ubi".
