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 and increased maxItems
to 4 for the interrupts and interrupt-names property.

We have a dedicated IRQ line specifically for the hibernation feature.
When the "wakeup" IRQ line is triggered, it initiates a hibernation
interrupt, causing the system to wake up from the hibernation state.
