arm64: dts: rockchip: add power-domain nodes on rk3368

A patch from »drm/rockchip: add display support for rk3368« in state Mailinglist for linux-kernel

From: Heiko Stuebner <heiko@...> Date: Fri, 14 Dec 2018 23:18:27 +0100

Commit-Message

Add the power-controller main node, the individual power domains below it and their used quality-of-service syscons on rk3368 and hook the power-domains to their user-devicenodes. Signed-off-by: Heiko Stuebner <heiko@...>
