This patch add support for RTC of Exynos3250 SoC. The Exynos3250 needs source
clock(32.768KHz) for RTC block. If source clock of RTC is registerd on clock
list of common clk framework, Exynos RTC drvier have to control this clock.
Clock list for s3c-rtc device:
- rtc : CLK_RTC
From: Chanwoo Choi
This patch fix wrong compatible string of Exynos3250 RTC (Real-Time Clock) dt
node. The RTC of Exynos3250 must need additional source clock (XrtcXTI).

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.

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

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 product Id and revision number.
