[PATCH v5 01/13] dt-bindings: net: mediatek,net: update for mt7988

[Frank Wunderlich]

From: Frank Wunderlich <frank-w at public-files.de>

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

MT7988 has 4 FE IRQs (currently only 2 are used) and the 4 IRQs for
use with RSS/LRO later.

Add interrupt-names to make them accessible by name.

v5:
- fix v4 logmessage and change description a bit describing how i get
  the irq count.
- update binding for 8 irqs with different names (rx,tx => fe0..fe3)
  including the 2 reserved irqs which can be used later
- change rx-ringX to pdmaX to be closer to hardware documentation

v4:
- increase max interrupts to 6 because of adding RSS/LRO interrupts (4)
  and dropping 2 reserved irqs (0+3) around rx+tx
- dropped Robs RB due to this change
- allow interrupt names
- add interrupt-names without reserved IRQs on mt7988
  this requires mtk driver patch:
  https://patchwork.kernel.org/project/netdevbpf/patch/20250616080738.117993-2-linux@fw-web.de/

v2:
- change reg to list of items
