Hi Rob,

Thank you for the review.

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

Use standard unit suffix and drop the type.
Sure will do in the next version.
