Currently the UART used by some Samsung SoCs is selected by the generic CONFIG_S5P define. This makes it hard to re-use that UART without pulling in the whole of the S5P code. Also the Exynos SoCs use this driver, which is in fact a generic Samsung UART driver. So create a new Kconfig symbol CONFIG_SAMSUNG_UART to reflect this and change the existing boards to use this symbol.
