[PATCH v4 01/13] dt-bindings: net: mediatek,net: update for mt7988

Update binding for mt7988 which has 3 gmac and 2 reg items.

With RSS-IRQs the interrupt max-items is now 6. Add interrupt-names
to make them accessible by name.

v4:
- increase max interrupts to 8 because of RSS/LRO interrupts
- dropped Robs RB due to this change
- allow interrupt names
- add interrupt-names without reserved IRQs on mt7988
this requires mtk driver patch:

v2:
- change reg to list of items
