[PATCH net-next v6 1/4] dt-bindings: net: Add tx and rx internal delays

[Dan Murphy <dmurphy@ti.com>]

tx-internal-delays and rx-internal-delays are a common setting for RGMII
capable devices.

These properties are used when the phy-mode or phy-controller is set to
rgmii-id, rgmii-rxid or rgmii-txid.  These modes indicate to the
controller that the PHY will add the internal delay for the connection.
