ipq40xx: utilize nvmem-cells for plasmacloud,pa1200
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.
