[PATCH v2 2/6] dt-bindings: nvmem: add max77759 binding

["André Draszik" <andre.draszik@linaro.org>]

The Maxim MAX77759 is a companion PMIC for USB Type-C applications and
includes Battery Charger, Fuel Gauge, temperature sensors, USB Type-C
Port Controller (TCPC), NVMEM, and a GPIO expander.

This describes its storage module (NVMEM).

v2:
* drop example as the MFD binding has a complete one (Rob)

Note: MAINTAINERS doesn't need updating, the binding update for the
first leaf device (gpio) adds a wildcard matching all max77759 bindings
