Add support for the R-Car V3M (R8A77970) SoC to the R-Car DU driver.
Signed-off-by: Sergei Shtylyov <sergei.shtylyov@xxxxxxxxxxxxxxxxxx>

Changes in version 2:
- removed the 'model' and 'dpll_ch' field initializers;
- fixed up the DU port numbers;
- split the DU bindings and the LVDS driver updates into a separate patches;
- removed the check before the DPTSR write (to be done in a separate patch).
