arm: exynos: i2c: Convert exynos boards to use DM_I2C 

Three boards are still not converting to use DM_I2C. They are also using
the old PMIC framework. Rather than removing them, add #ifdefs to allow
them to continue to build. This will give the maintainers a little more
time to decide whether to convert them or not.
