This patch series attempts to get rid of soc_is_exynos macros
and eventually with the help of this series we can probably get
rid of CONFIG_SOC_EXYNOS in near future.
Each Exynos SoC has ChipID block which can give information about
SoC's

Let's handle i2c interrupt re-configuration in i2c driver. This will
help us in removing some soc specific checks from machine files.
Since only Exynos5250, and Exynos5420 need to do this, added syscon
based phandle to i2c device nodes of respective SoC

This patch enables chipid driver for ARCH_EXYNOS and refactors
machine code as well as exynos cpufreq driver code for using
chipid driver for identification of SoC ID and SoC rev.

Since all these code has been moved into i2c driver, now we can
safely remove them from machine files.

This patch removes usage of soc_is_exynos4/5 from exynos.c.
For this we need to separate machine descriptors for exynos4
and exynos5. While doing this patch does some consolidation also.
