ARM: dts: add dtsi for exynos7870-on7xelte (Samsung Galaxy J7 Prime)

Add a framebuffer node to the DTSI in order to ensure that display
continues to work, as since v6.19 of devicetree-rebasing sources, it
uses Samsung's DECON (Display Enhancement CONtroller) for display, which
is, as of yet, not supported in U-Boot.
