[RFC PATCH 1/3] dt-bindings: pinctrl: jh7110-sys: add force inputs

[Icenowy Zheng]

The internal inputs routed by the pin controller could be routed not to
any GPIOs but forced low/high in the pin controller, which is a useful
feature for some input signals (e.g. overcurrent_n pin of the USB
controller, which needs to be tied to high if not externally routed).

Add two properties to support forcing inputs to low/high.
