    ath79: make Engenius fakeroot partitions read-only
    
    For:
    
     - ENH202 v1
     - ENS202EXT v1
    
    These boards were committed before it was discovered
    that for all Engenius boards with a "failsafe" image,
    forcing the failsafe image to load next boot
    can be achieved by editing the u-boot environment like:
    
      `fw_setenv rootfs_checksum 0`
    
    So it's not necessary to delete a partition to boot to failsafe image.
