Subject: [PATCH v2 3/3] arm64: dts: rockchip: add dual-role usb3 hosts to rk3588 Tiger-Haikou

From: Heiko Stuebner <heiko.stuebner@...rry.de>

Apart from the host-only usb3 controller (host2) the rk3588 also provides
two dual-role controllers. On the Tiger-Haikou combination these are
connected to the lower usb3-host port in host-only mode and the micro-usb3
port for dual-role operation.

Add the necessary controllers, phys to the Tiger-Haikou board and enable
the usb-id extcon.
