nvmem: add support for nvmem-cells binding
Recently, nvmem cell and MTD partition bindings were made to coexist:
Partitions can now be compatible = "nvmem-cells"; which registers a
NVMEM provider and interprets its child nodes as cells. Teach barebox
about this. This allows fetching NVMEM cells from MTD partitions and
hostfiles.
