Subject: [PATCH] ARM: dts: blanche: add DU support

Define  the  Blanche 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.
