[PATCH 7/8] rockchip: rk3368: sync down rk3368-lion board devicetree from Linux

[Heiko Stuebner <heiko@sntech.de>]

From: Heiko Stuebner <heiko.stuebner@theobroma-systems.com>

This brings the actual rk3368-lion devicetree files from Linux 5.10
instead of using something separate.

Signed-off-by: Heiko Stuebner <heiko.stuebner@theobroma-systems.com>
