arm64: dts: exynos7870-j6lte: enable display panel support
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 AMS561RA01 panel with
S6E8AA5X01 controller.
