[PATCH net-next v2 1/7] dt-bindings: net: mediatek-dwmac: add support for MT8189 SoC

[Louis-Alexis Eyraud]

Add new compatible string and clock definitions for the Ethernet MAC
IP found in MT8189 SoC.

Also, update "mediatek,rx-delay-ps" and "mediatek,tx-delay-ps" property
description to add MT8189 RX/TX delay stage divider values, as they
differ from existing supported SoC.
