Subject: [PATCH 1/3] arm64: dts: rockchip: add mipi dcphy nodes to rk3588

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

Add the two MIPI-DC-phy nodes to the RK3588, that will be used by the
DSI2 controllers and hopefully in some future also for camera input.

Signed-off-by: Heiko Stuebner <heiko.stuebner@...rry.de>
