High speed I2C is used on Exynos5 based SoCs. Enable it.

The MMC partition for Root filesystem cannot be mounted
without this enabling HS-I2C and regulators on many boards
are connected HS-I2C bus so the regulators don't come by
default without this.

Actually, we are not able to get arndale-octa board to boot
and mount an MMC partition without this change.
