gpio: add DT binding doc for gpio of PMIC max77620/max20024

Maxim Semiconductor's PMIC MAX77620/MAX20024 has 8 GPIO pins
which act as GPIO as well as special function mode.

Add DT binding document to support these pins in GPIO
mode via GPIO framework.

GPIO driver for MAX77620 Power management IC from Maxim Semiconductor.
Device has 8 GPIO pins which can be configured as GPIO as well as the
special IO functions.
Required properties:
-------------------
- gpio-controller : Marks the device node as a gpio controller.
- #gpio-cells : Should be two. The first cell is the pin number and
the second cell is used to specify the gpio polarity:
0 = active high
1 = active low
For more details, please refer generic GPIO DT binding document
<devicetree/bindings/gpio/gpio.txt>.
Example:
--------
#include <dt-bindings/mfd/max77620.h>
...
max77620@3c {
compatible = "maxim,max77620";
gpio-controller;
#gpio-cells = <2>;
};
