Hm, maybe I don't get it right, but this looks suspicious. Usually the
consumer lookup table is here to attach device specific names to
external resources.

So what I'd expect here is:

struct nvmem_cell_lookup {
	/* The nvmem device name. */
	const char *nvmem_name;

	/* The nvmem cell name */
	const char *nvmem_cell_name;

	/*
	 * The local resource name. Basically what you have in the
	 * nvmem-cell-names prop.
	 */
	const char *conid;
};

struct nvmem_cell_lookup_table {
	struct list_head list;

	/* ID of the consumer device. */
	const char *devid;

	/* Array of cell lookup entries. */
	unsigned int ncells;
	const struct nvmem_cell_lookup *cells;
};

Looks like your nvmem_cell_lookup is more something used to attach cells
to an nvmem device, which is NVMEM provider's responsibility not the
consumer one.
