dt-bindings: net: meson-dwmac: Add the amlogic,rx-delay-ns property

The PRG_ETHERNET registers on Meson8b and newer SoCs can add an RX
delay. Add a property with the known supported values so it can be
configured according to the board layout.

The internal RGMII RX clock delay (provided by this IP block) in
nanoseconds. When phy-mode is set to "rgmii" then the RX delay
should be explicitly configured. When the phy-mode is set to

provided by the PHY. Any configuration is ignored when the
phy-mode is set to "rmii".
