Subject: [PATCH v3 3/4] dt-bindings: at24: remove the optional property write-protect-gpios

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.

Removing the optional property form the device tree binding document.
