Subject: [PATCH V2] dt-bindings: usb: dwc3: Add interrupt-names property support for wakeup interrupt

The hibernation feature enabled for Xilinx Versal NET SoC in DWC3 IP.
As the DWC3 IP supports the hibernation feature, to handle the wakeup
or hibernation interrupt, add host mode "wakeup" interrupt-names
optional property in the binding schema to capture remote-wakeup and
connect/ disconnect event in the hibernation state.

Signed-off-by: Piyush Mehta <piyush.mehta@....com>

Change in V2:
-  Addressed ROB review comments
 - Updated name of interrupt-names property with "wakeup"
 - Move interrupt-names property from dwc3-xilinx core to dwc3 core.
