    ipq40xx: utilize nvmem-cells for openmesh,a42
    
    The calibration data and mac addresses on this device are stored in the
    0:ART partition. It is therefore possible to move the code to handle them
    directly to the devicetree instead of the various scripts.
    
    But the actual relevant information about the partition layout is provided
    by the bootloader via bootargs (mtdparts) and not via the devicetree
    itself. Instead of using a fixed-partition template, the mtd dynamic
    partitions support from the upstream kernel is used.
