[PATCH 08/10] ARM: dts: sun4i: Enable HDMI support on some A10 devices

Various A10-based development boards have standard HDMI connectors
wired to the dedicated HDMI pins on the SoC.

Enable the display pipeline and HDMI output on boards I have or have
access to schematics:

  - Cubieboard
  - Olimex A10-OLinuXino-LIME

Can someone could double check the LIME for me? It should work given
it's the same layout as the A20 variant, which has been tested.
