After Vladimir answer I know that it should be a separate change.
I need it for MAC <-> switch connection, the rgmii port connected to
the cpu. At this moment, rgmii delays are hardcoded in vsc73xx_setup
and it should be tunable for the p2020rdb board. I plan to work on it
after the driver becomes usable.
