Document new dynamic-partitions node used to provide an of node for partition registred at runtime by parsers. This is required for nvmem system to declare and detect nvmem-cells.

Example are + partitions declared from smem parser or cmdlinepart. This will create an + of node for these dynamic partition where systems like Nvmem can get a + reference to register nvmem-cells. + + The partition table should be a node named "dynamic-partitions". + Partitions are then defined as subnodes.
