Update block NVMEM driver based on backported OF partition support. Note the different MMC card DT binding compared to the previous downstream solution: Instead of having a 'partitions' subnode inside a 'block' node, the 'partitions' node now resides directly under the node representing the card. In order to make references to the 'boot0' or 'boot1' hw partitions you will have to define 'partitions-boot0' or 'partitions-boot1', and move the NVMEM layout into a partition (you may, of course, use 'fixed-partitions' for that, and cover the whole device, if needed).
