Subject: [PATCH v4] dt-bindings: net: wireless: mt76: add interrupts description for MT7986

The mt7986 can support four interrupts to distribute the interrupts
to different CPUs.

v2: Change to use description instead of using items.
v3: Change to use items and set different minItems for mediatek,mt7986-wmac
v4: Move allOf after required and remove duplicated blank line.
