[PATCH v2 1/2] dt-bindings: serial: samsung: Add samsung,exynos8895-uart compatible

[Ivaylo Ivanov]

Add dedicated samsung,exynos8895-uart compatible to the dt-schema for
representing uart of the Exynos8895 SoC.

Like GS101, it has a required DT property samsung,uart-fifosize, but
it does not exhibit the 32 bit register access limit.
