[PATCH 09/10] ARM: dts: sun7i: Add device nodes for display pipelines

[wens@csie.org (Chen-Yu Tsai)]

From: Jonathan Liu <net147@gmail.com>

The A20 has two interconnected display pipelines, mirroring the A10.

Add all the device nodes for them, including the downstream HDMI
controller that we already support.
