    uboot-envtools: mvebu: update uci defaults for Turris Omnia
    
    From version 2021.09 U-Boot will fixup Turris Omnia's DTB before
    booting, separating U-Boot's environment into separate MTD partition
    "u-boot-env" [1].
    
    Check if "u-boot-env" MTD partition exists and set the uci defaults
    accordingly.
