[PATCH v2 4/5] dt-bindings: phy-rockchip-inno-usb2: add otg mux irq quirk

[Frank Wang <frank.wang-TNX95d0MmH7DzftRWevZcw@public.gmane.org>]

Add rockchip,otg_mux_irq_quirk property to support the otg-id/
otg-bvalid/linestate irqs that are multiplexed to one irq in
otg-port on some special Rockchip SoCs (e.g RV1108).
