[PATCH v2 6/6] arm64: dts: exynos7870-j6lte: enable display panel support

[Kaustabh Chakraborty]

Enable DECON and DSI nodes, and add the compatible display panel and
appropriate panel timings for this device. Also, remove the
simple-framebuffer node in favor of the panel.

This device has a 720x1480 AMOLED Samsung S6E8AA5X01 display panel.
