dt-bindings: serial: samsung: add samsung,exynos2200-uart compatible

Add dedicated samsung,exynos2200-uart compatible to the dt-schema for
representing uart of the exynos2200.

Like GS101, it has a required DT property samsung,uart-fifosize and
exhibits the 32 bit register access limit, so reuse support for it.
