usb: dwc3: qcom: Add multiport suspend/resume support for wrapper

Power event IRQ is used for wakeup either when the controller is
SuperSpeed capable but is missing an SuperSpeed PHY interrupt, or when
the GIC is not capable of detecting DP/DM High-Speed PHY interrupts.

The Power event IRQ stat register indicates whether the High-Speed
phy entered and exited L2 successfully during suspend and resume.
Indicate the same for all ports of a multiport controller.
