FROMLIST: dt-bindings: add document for analogix display port driver

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.

+       -reg:
+               physical base address of the controller and length
+               of memory mapped region.
+       -interrupts:
+               interrupt combiner values.
+       -clocks:
+               from common clock binding: handle to dp clock.
+       -clock-names:
+               from common clock binding: Shall be "dp".
+       -interrupt-parent:
+               phandle to Interrupt combiner node.

+               from general PHY binding: the phandle for the PHY device.
+       -phy-names:
+               from general PHY binding: Should be "dp".

+       -hpd-gpios:
+               Hotplug detect GPIO.
+               Indicates which GPIO should be used for hotplug detection
+       -port@[X]: SoC specific port nodes with endpoint definitions as defined
