ARM: EXYNOS: add initial setup-i2c0 for EXYNOS5

In all of Samsung platform, the setup-i2c0.c file for I2C channel 0 is always compiled. So when supporting new SoC,it should be updated for it. Since EXYNOS5 GPIO will be supported after this, there is no setup gpio in there now. It will be implemented with that, of course. Signed-off-by: Kukjin Kim <[email protected]>
