This does not cover providers whose device tree node is itself the fixed-layout container, such as an eMMC boot partition block device whose fwnode points directly at a "fixed-layout" compatible partitions node. When no "nvmem-layout" child is present, fall back to returning the nvmem device node itself if it is compatible with "fixed-layout", so that its cells are parsed by nvmem_add_cells_from_fixed_layout().
