[PATCH v3 1/2] dt-bindings: hwmon: Add AST2700 compatible

Adds support for the AST2700 PWM/Tach controller by extending the
compatible string enumeration in the device tree binding.

The AST2700 PWM/Tach hardware is compatible with the existing binding
schema and requires no additional properties or modifications beyond
the new compatible string.
