    uboot-envtools: Add support for IPQ806x AP148 and DB149
    
    IPQ806x AP148 and DB149 boards didn't have the UCI ubootenv
    section initialized, so the usage of fw_printenv required manual
    configuration. With this change, the "fw_printenv" and "fw_setenv"
    command will automatically work on NOR and NAND based platforms.
