Subject: [PATCH v4 3/5] dt-bindings: at24: make wp-gpios a reference to the property defined by nvmem

NVMEM framework is an interface for the at24 EEPROMs as well as for
other drivers, instead of passing the wp-gpios over the different
drivers each time, it would be better to pass it over the NVMEM
subsystem once and for all.

Making wp-gpios a reference to the property defined by nvmem.
