Declare Exynos5422/5800 voltage ranges for opp points for big cpu core and
bus wcore and couple their voltage supllies as vdd_arm and vdd_int should
be in 300mV range.

This patch is the same as https://patchwork.kernel.org/patch/11172427/
which has been dropped due to the other issues in the regulator framework.
Those issues has been resolved now, so it is safe to apply it.
