[PATCH v9 02/13] dt-bindings: net: mediatek,net: allow up to 8 IRQs

[Frank Wunderlich]

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

Increase the maximum IRQ count to 8 (4 FE + 4 RSS/LRO).

Frame-engine-IRQs (max 4):
MT7621, MT7628: 1 FE-IRQ
MT7622, MT7623: 3 FE-IRQs (only two used by the driver for now)
MT7981, MT7986, MT7988: 4 FE-IRQs (only two used by the driver for now)

Mediatek Filogic SoCs (mt798x) have 4 additional IRQs for RSS and/or
LRO. So MT798x have 8 IRQs in total.

MT7981 does not have a ethernet-node yet.
MT7986 Ethernet node is updated with RSS/LRO IRQs in this series.
MT7988 Ethernet node is added in this series.

v9:
- set interrupt minitems to 8 for filogic
  - mt7981 does not have a ethernet node yet, so no ABI break
  - devicetree for mt7986 is updated later in this series, ABI-Break,
    but RSS/LRO should use interrupt names and is simply disabled when
    using older DT
- extend mt7986 example with PDMA-IRQs because minItems now 8
v8: separate irq-count change from interrupt-names patch
