[PATCH] arm64: zynqmp: Fix dwc3 usb interrupt description

Based on DT binding dwc_usb3 is single entry without anything else. That's
why combination dwc3_usb3, otg is not allowed. That's why split it to host
and peripheral pair which both points to the same IRQ.
DWC3 code is reading these two properties first before generic dwc_usb3.
