[PATCH 10/25] ARM: dts: rockchip: Add USB2 PHY and USB3-OTG (DWC3) nodes for RV1106

[Vladislav Leonov <vlad@zlab.su>]

Add the u2phy node with its otg-port child, using the disconnect
interrupt in addition to otg-bvalid/otg-id/linestate.

Also add the usbdrd/usbdrd_dwc3 nodes for the DWC3 controller behind
the PHY, reusing the "rockchip,rk3399-dwc3" glue compatible and the
snps quirks already used by other Rockchip DWC3 platforms, since
RV1106 does not need a dedicated glue driver.

Both nodes default to status = "disabled" and are enabled per-board.
