dt-bindings: nvmem: consumer: Make 'nvmem' an array of one-item entries

'nvmem' unlike 'nvmem-cells', consumes references to just a single
phandle with no arguments (i.e. with 0 cells).

Constrain the schema to enforce that, so that the number of such
single-item entries can then be regulated by IP block-specific YAMLs.
