net: phy: dp83867: allow RGMII_TXID/RGMII_RXID interface types
Currently dp83867 driver returns error if phy interface type PHY_INTERFACE_MODE_RGMII_RXID is used to set the rx only internal delay. Similarly issue happens for PHY_INTERFACE_MODE_RGMII_TXID. Fix this by checking also the interface type if a particular delay value is missing in the phy dt bindings. Also update the DT document accordingly.
