[PATCH 1/2] dt-bindings: pincfg-node: Add "input-schmitt-microvolt" property

[Inochi Amaoto <inochiama@xxxxxxxxxxx>]

On Sophgo CV18XX platform, threshold strength of schmitt trigger can
be configured. As this standard property is already supported by the
common pinconf code. Add "input-schmitt-microvolt" property in
pincfg-node.yaml so that other platforms requiring such feature can
make use of this property.
