nvmem: layouts: Support fixed-layout as the nvmem device node itself

of_nvmem_layout_get_container() only looks for a child node named
"nvmem-layout" to locate the cell definitions. 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().
