    lantiq: nand: drop ubifs images
    
    Users are confused which image type they should use and there are more
    drawbacks than adavantages in using a r/w ubifs rootfs in constrast to
    a read-only squashfs rootfs like:
    
     - less available free flash space due to better compression of squashfs
       images
     - no support for factory reset due to r/w filesystem
     - possibility to break failsafe due to r/w filesystem
    
    Therefore, drop support for r/w ubifs rootfs images.
