The bootloader adds MTD partitions in this subnode if present, or in the spi-nor node itself otherwise. Setting #size-cells in MTD nodes itself is deprecated by mtd.yaml. Fix all this by adding an empty partitions node which the bootloader will fill with configured MTD partitions. Remove the deprecated properties as well.
