Subject: [PATCH] On SPARCbook systems, the ledma device node has a
 `cable-selection' property specifying which media the on-board interface
 uses. We already query it to set up proper register values; extend this to be
 able to pass a default media to the le(4) child.

This makes SPARCbook system default to AUI without needing for a manual media
change.
