[PATCH v3] dt-bindings: serial: samsung: add exynos7870-uart compatible

[Kaustabh Chakraborty]

Document the compatible string for Exynos7870's UART driver. The
devicetree property samsung,uart-fifosize must be mandatory, as the
driver enquires about the FIFO sizes. This feature makes it compatible
with Exynos8895's UART.
