[PATCH 4/4] arm64: dts: rockchip: Add HUSB311 Type-C controller on RK3576 EVB1

[Alexey Charkov <alchark@flipper.net>]

Rockchip RK3576 EVB1 board has a Hynetek HUSB311 USB Type-C controller on
its Type-C OTG port, which also supports DisplayPort Alternate Mode.

Add the required DT nodes to enable basic HUSB311 operation.

Note that for full support of mode and orientation switching, the USBDP
PHY schema may need to be expanded, such as in [1]. This is left out for
now until the respective schema is finalized and merged.
