dt-bindings: usb: qcom,dwc3: fix interrupt max items

A recent commit adding the SC8280XP multiport controller to the binding
failed to update the interrupt maxItems, which results it DT checker
warnings like:

	arch/arm64/boot/dts/qcom/sc8280xp-lenovo-thinkpad-x13s.dtb: usb@a4f8800: interrupts-extended: [[1, 0, 130, 4], [1, 0, 135, 4], [1, 0, 857, 4], [1, 0, 856, 4], [1, 0, 131, 4], [1, 0, 136, 4], [1, 0, 860, 4], [1, 0, 859, 4], [136, 127, 3], [136, 126, 3], [136, 129, 3], [136, 128, 3], [136, 131, 3], [136, 130, 3], [136, 133, 3], [136, 132, 3], [136, 16, 4], [136, 17, 4]] is too long
