====================
dsa: mv88e6xxx: Fixes for port refactoring

The patches which refactored setting up the switch MACs introduced a
couple of regressions. The RGMII delays for a port can be set using
other mechanism than just phy-mode. Don't overwrite the delays unless
explicitly asked to. This broke my Armada 370 RD. Also, the mv88e6351
family supports setting RGMII delays, but is missing the necessary
entries in the ops structures to allow this.

These fixes are to patches currently in net-next. No need for stable
etc.
