Documentation: networking: dsa: remove references to switchdev prepare/commit
After the recent series containing commit bae33f2b5afe ("net: switchdev:
remove the transaction structure from port attributes"), there aren't
prepare/commit transactional phases anymore in most of the switchdev
objects/attributes, and as a result, there aren't any in the DSA driver
API either. So remove this piece.
