[PATCH] dt-bindings: usb: dwc3: xilinx: Add interrupt-names to include hibernation interrupt

[Piyush Mehta]

The hibernation feature enabled for Xilinx Versal NET SoC in DWC3 IP.
Added host mode interrupts and "usb-wakeup" interrupt-names optional
property in the binding schema to capture remote-wakeup and connect/
disconnect event in the hibernation state.

Xilinx dwc3-core uses "host" and "otg" interrupts interrupt-names DT
properties from dwc3-core.
