arm64: dts: rockchip: add usb typec host support to

A patch from ğarm64: dts: rockchip: add usb typec host support toĞ in state Mainline for linux-kernel

Commit-Message

Jaguar has two type-c ports connected to fusb302 controllers that can work both in host and device mode and can also run in display-port altmode. While these ports can work in dual-role data mode, they do not support powering the device itself as power-sink. This causes issues because the current infrastructure does not cope well with dual-role data without dual-role power. So add the necessary nodes for the type-c controllers as well as enable the relevant core usb nodes, but limit the mode to host-mode for now until we figure out device mode.
