If nvmem_add_cells() fails, the whole nvmem_register() will fail
and the cells will then be removed anyway. This is a prepartion
to introduce a nvmem_add_one_cell() which can then be used by
nvmem_add_cells().

This is then the same to what nvmem_add_cells_from_table() and
nvmem_add_cells_from_of() do.
