This will be a subnode of the nvme controller node that will have the "nvme-card" compatible. This follow a similar implementation done for mmc where the specific mmc card have a dedicated of_node. This can be used for scenario where block2mtd module is used to declare partition in DT and block2mtd is called on the root block of the nvme card, permitting the usage of fixed-partition parser or alternative ones.
