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 DT files.
Also handle saving and restoring of SYS_I2C_CFG register during
suspend and resume of i2c driver. This will help in removing soc
specific check from mach-exynos/pm.c.

Shall this go via i2c-tree? Looks to me like it should go with the rest
of the series? Patch is mostly okay (only reviewed the code, not the
bindings), one nit:

+	regmap_update_bits(i2c->sysreg, EXYNOS5_SYS_I2C_CFG, BIT(id), val);

Hardcode the '0' and drop using 'val'?
