Subject: [PATCH v3 2/3] dt-bindings: hwmon: g76x: Add support for g761

Add support for g761 PWM Fan controller. This is an exact copy of g763
with the difference that it does also support an internal clock
oscillator.

With clocks property not defined, the internal clock oscillator is used.

+  G761 supports an internal-clock hence the clocks property is optional.
+  If not defined, internal-clock will be used. (31KHz is the clock of
+  the internal crystal oscillator)
 
   If an optional property is not set in DT, then current value is kept
   unmodified (e.g. bootloader installed value).
