ARM: dts: sun8i-a33: Move display pipeline nodes to a23/a33 common dtsi
The display pipeline has the same structure, resources and connections on both the A23 and A33. The differences include: - compatible strings - extra clock, reset control, and IO region for SAT in the backend only found on the A33 - missing ch1 clock for the TCON However, while the A23 has the TCON ch1 clock defined in the CCU, and the channel 1 registers are available, it does not have any means to use channel 1 due to a lack of downstream encoders, and the enable bit for channel 1 is hard-wired to 0 (off). As the MIPI DSI output device is not officially documented, and there are no A23 reference devices to test it, it is not covered by this patch.
