[PATCH v2 1/3] dt-bindings: pinctrl: starfive,jh7110: add PAD_INTERNAL_* virtual pins

[Icenowy Zheng]

The JH7110 SoC could support internal GPI signals to be routed to not
external GPIO but internal low/high levels.

Add two macros, PAD_INTERNAL_LOW and PAD_INTERNAL_HIGH, as two virtual
"pads" to represent internal GPI sources with fixed low/high levels.
