[RFC PATCH net-next v3 7/8] dt-bindings: net: mediatek,net: fix and complete mt7988-eth binding

[Daniel Golle <daniel@makrotopia.org>]

Complete support for MT7988 which comes with 3 MACs, SRAM for DMA
descriptors and uses a dedicated PCS for the SerDes units.

Fixes: c94a9aabec36 ("dt-bindings: net: mediatek,net: add mt7988-eth binding")
