The lan969x switch device supports two RGMII port interfaces that can be
configured for MAC level rx and tx delays.
Document two new properties {rx,tx}-internal-delay-ps. Make them
required properties, if the phy-mode is one of: rgmii, rgmii_id,
rgmii-rxid or rgmii-txid. Also specify accepted values.
