dt-bindings: usb: qcom,dwc3: Add bindings for SC8280 Multiport

Add the compatible string for SC8280 Multiport USB controller from
Qualcomm.

There are 4 power event interrupts supported by this controller
(one for each port of multiport controller). Add all the 4 as
non-optional interrupts for SC8280XP-MP

Also each port of multiport has one DP and one DM IRQ. Add all DP/DM
IRQs related to 4 ports of SC8280XP Teritiary controller.

Also added SuperSpeed PHY interrupt for both Superspeed ports.
