Thus this should really be in the nvmem-provider's header. There are two (unused) nvmem access methods which use the nvmem_cell_info to describe the cell to be accesses. One can argue, that they will create a cell before accessing, thus they are both a provider and a consumer. struct nvmem_cell_info will get used more and more by nvmem-providers, don't force them to also include the consumer header, although they are not.
