[PATCH] dt-bindings: pincfg-node: Add "input-schmitt" 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" property in pincfg-node.yaml
so that other platforms requiring such feature can make use of this
property.
