dt-bindings: at24: add Renesas R1EX24016

Document the compatible value for the Renesas R1EX24128ASAS0A two-wire
serial interface EEPROM, so it can be used in DTS files without causing
checkpatch warnings.

This is a 2 KiB EEPROM. The first 1 KiB can always be written, the
second 1 KiB cannot be written if the write-protect line is asserted.
