[PATCH v4] arm64: dts: renesas: condor/v3hsk: add DU/LVDS/HDMI support

[Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>]

Define the Condor/V3HSK board dependent parts of the DU and  LVDS device
nodes. Also add the device nodes for Thine THC63LVD1024 LVDS decoder and
Analog Devices ADV7511W HDMI transmitter...

Based on the original (and large) patch by Vladimir Barinov.

---
The patch is against the 'renesas-devel-20180822-v4.18' tag of Simon Horman's
'renesas.git' repo. The only driver support still unmerged seems to be the
R8A77980 LVDS support patches...

Changes in version 4:
- added the OSC1 clock node and a reference to it from the DU device node in
  the V3HSK board DT;
- added Ulrich's and Laurent's tags.

Changes in version 2:
- added the V3HSK DT update, reworded the description, renamed the patch;
- added a space between the HDMI node name and a brace.
