    ath79: convert WiFis based on ar7241_ubnt_unifi.dtsi to nvmem-cells
    
    Pull the calibration data from the nvmem subsystem. This allows us to
    move userspace caldata extraction into the device-tree definition.
    
    While working on it remove stale uboot partition label and merge art
    into partition node.
