Subject: [PATCH v1 24/50] ARM: dts: exynos: align OPPs with PLL rate for
 MSCL in Exynos5420

The OPPs must reflect possible values after dividing the master clock.
The old values 400 and 333, 222, etc does not have common parent rate.
Thus, align the values to parent rate such that they will be set exactly
using only a divider.
