Define the generic R8A77970 part of the LVDS device node.

Signed-off-by: Sergei Shtylyov <sergei.shtylyov at cogentembedded.com>

Changes in version 2:
- resolved rejects and updated atop of the DU support patch;
- changed the LVDS node's label/name;
- renamed the input/output endpoints' labels;
- added the "power-domains" and "resets" properties.
