Subject: [PATCH v2 3/3] arm64: dts: rockchip: rk3588s: Add USB3 host controller

RK3588 has three USB3 controllers. This adds the host-only controller,
which is using the naneng-combphy shared with PCIe and SATA.

The other two are dual-role and using a different PHY that is not yet
supported upstream.
