Subject: [PATCH 1/3] arm64: dts: rockchip: Fix the panel compatible for the
 PinePhone Pro

As documented in its bindings, the compatible for the Himax HX8394
MIPI-DSI LCD panel controller is in 2 parts.
The PinePhone Pro DTS currently only specifies the first part of the
compatible, generating a warning.
