    ath79: ubnt-unifi: make u-boot-env partition read-only
    
    This partition isn't normally modified during boot process. Make it
    read-only to prevent accidental overwrite.
    If needed this can be overriden with installing kmod-mtd-rw; the same
    way as for installing modified U-boot.
