nvmem: Move of_nvmem_layout_get_container() in another header
nvmem-consumer.h is included by consumer devices, extracting data from
NVMEM devices whereas nvmem-provider.h is included by devices providing
NVMEM content.
The only users of of_nvmem_layout_get_container() outside of the core
are layout drivers, so better move its prototype to nvmem-provider.h.
While we do so, we also move the kdoc associated with the function to
the header rather than the .c file.
