Subject: [PATCH v2 1/3] dt-bindings: hwmon: g762: Convert to yaml schema

Convert g762 Documentation to yaml schema.

Since it supports various device, change the name to g76x and add the
vendor prefix.

-GMT G762/G763 PWM Fan controller
-
-Required node properties:
-
- - "compatible": must be either "gmt,g762" or "gmt,g763"
- - "reg": I2C bus address of the device
- - "clocks": a fixed clock providing input clock frequency
-	     on CLK pin of the chip.
-
-Optional properties:
-
- - "fan_startv": fan startup voltage. Accepted values are 0, 1, 2 and 3.
-	       The higher the more.
-
- - "pwm_polarity": pwm polarity. Accepted values are 0 (positive duty)
-	       and 1 (negative duty).
-
- - "fan_gear_mode": fan gear mode. Supported values are 0, 1 and 2.
-
-If an optional property is not set in .dts file, then current value is kept
-unmodified (e.g. u-boot installed value).
-
-Additional information on operational parameters for the device is available
-in Documentation/hwmon/g762.rst. A detailed datasheet for the device is available
-at http://natisbad.org/NAS/refs/GMT_EDS-762_763-080710-0.2.pdf.

-	#size-cells = <0>;
-

-		 #clock-cells = <0>;
-		 clock-frequency = <8192>;

-   g762: g762@3e {

-	fan_gear_mode = <0>; /* chip default */
