[PATCH v3 2/4] dt-bindings: pinctrl: spacemit: add K3 SoC support

[Yixun Lan]

Add new compatible string for SpacemiT K3 SoC, the pinctrl IP shares
almost same logic with previous K1 generation, but has different register
offset and pin configuration, for example the drive strength and
schmitter trigger settings has been changed.
