dt-bindings: display: rcar-du: Document R8A774[35] DU

Browse Source 
Add device tree bindings for r8a7743 and r8a7745 DUs.
r8a7743 DU is similar to the one from r8a7791, r8a7745 DU is similar
to the one from r8a7794.

- clock-names: Name of the clocks. This property is model-dependent.
- R8A7779 uses a single functional clock. The clock doesn't need to be
named.
- R8A779[0123456] use one functional clock per channel and one clock per
LVDS encoder (if available). The functional clocks must be named "du.x"
with "x" being the channel numerical index. The LVDS clocks must be
named "lvds.x" with "x" being the LVDS encoder numerical index.
- All other DU instances use one functional clock per channel and one
clock per LVDS encoder (if available). The functional clocks must be
named "du.x" with "x" being the channel numerical index. The LVDS clocks
must be named "lvds.x" with "x" being the LVDS encoder numerical index.
- In addition to the functional and encoder clocks, all DU versions also
support externally supplied pixel clocks. Those clocks are optional.
When supplied they must be named "dclkin.x" with "x" being the input
