ARM: shmobile: silk: add DU DT support

Commit Message

Define  the SILK board dependent part of the DU device node.
Add the device nodes for the Analog Devices ADV7511W HDMI transmitter
(connected to DU0) and ADV7123  video DAC (connected to DU1). Add the
necessary subnodes to interconnect DU, HDMI/VDAC devices, and HDMI/VGA
connectors.

Thanks, I have queued this up for v4.6 after updating the subject with
s/shmobile/dts/ to reflect a request made from the ARM SoC maintainers
regarding prefixes for DT patches.
