[PATCH 6/7] arm64: dts: allwinner: a523: add DWC3 USB3.0 node

[iuncuim <iuncuim@gmail.com>]

From: Mikhail Kalashnikov <iuncuim@gmail.com>

After adding the phy bindings, we can also add dwc3 node, which uses the
previously added usbphy2 and part of usb3 from combophy.
All settings declared in dwc3 node are obtained from the x96qproplus' dtb.
BSP contains an additional glue driver for dwc3, but it seems that it is
not needed.
