Analogix dp driver is split from exynos dp driver, so we just
make an copy of exynos_dp.txt, and then simplify exynos_dp.txt

Beside update some exynos dtsi file with the latest change
according to the devicetree binding documents.

Signed-off-by: Yakir Yang <y...@rock-chips.com>
---
Changes in v3:
- Take Heiko suggest, add devicetree binding documents.
- Take Thierry Reding suggest, remove sync pol & colorimetry properies
  from the new analogix dp driver devicetree binding.
- Update the exist exynos dtsi file with the latest DP DT properies.

Changes in v2: None
