[PATCH v2 5/6] arm64: dts: exynos7870-a2corelte: 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 540x960 Synaptics TD4101 display panel.
