ARM: dts: exynos: Use common macros for pinctrl configuration
Replace duplicated macros in each DTSI file with a common macro coming from header. Include the header in each pinctrl DTSI so further changes could use it. Although PIN_FUNC_SPC_2 does not bring much information about the function itself, it still is more descriptive then hard-coded number <2>.
