[PATCH v5 07/21] nvmem: core: move struct nvmem_cell_info to nvmem-provider.h

struct nvmem_cell_info is used to describe a cell. 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.
