Subject: [PATCH 1/4] dt-bindings: pincfg-node: Add "output-impedance-ohms" property

On RZ/G2L SoC for Group-B pins, output impedance can be configured. This
patch documents "output-impedance-ohms" property in pincfg-node.yaml so
that other platforms requiring such feature can make use of this property.
