Samuel Holland 5bc9dd160d phy: rockchip-inno-usb2: Fix muxed interrupt support 
[ Upstream commit 6a98df08cc ]

This commit fixes two issues with the muxed interrupt handler. First,
the OTG port has the "bvalid" interrupt enabled, not "linestate". Since
only the linestate interrupt was handled, and not the bvalid interrupt,
plugging in a cable to the OTG port caused an interrupt storm.

Second, the return values from the individual port IRQ handlers need to
be OR-ed together. Otherwise, the lack of an interrupt from the last
port would cause the handler to erroneously return IRQ_NONE.

Fixes: ed2b5a8e6b ("phy: phy-rockchip-inno-usb2: support muxed interrupts")
