[PATCH] dt-bindings: mt76: allow up to 4 interrupts for mt7986

[Frank Wunderlich]

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

Mt7986 needs 4 interrupts which are already defined in mt7986a.dtsi.
Update binding to reflect it

This fixes this error in dtbs_check (here only bpi-r3 example):

arch/arm64/boot/dts/mediatek/mt7986a-bananapi-bpi-r3.dtb: wifi at 18000000:
interrupts: [[0, 213, 4], [0, 214, 4], [0, 215, 4], [0, 216, 4]] is too long
	From schema: Documentation/devicetree/bindings/net/wireless/mediatek,mt76.yaml
arch/arm64/boot/dts/mediatek/mt7986a-bananapi-bpi-r3.dtb: wifi at 18000000:
Unevaluated properties are not allowed ('interrupts' was unexpected)
	From schema: Documentation/devicetree/bindings/net/wireless/mediatek,mt76.yaml
