ARM: dts: silk: add DU DT support

Browse source 
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.
