[PATCH 1/9] ARM: dts: exynos: Add macros for GPIO configuration

Add macros for replacing hard-coded GPIO configuration: pull up/down,
drive strength and function.

Although PIN_FUNC_SPC_2 does not bring much information about the
function itself, it still is more descriptive then hard-coded
number <2>.
