Subject: [PATCH v1 42/50] ARM: dts: exynos: change parent and rate of
 bus_mscl in Exynos5422

The bus_mscl OPP table has been aligned to the new parent rate. This patch
sets the proper parents in the clock tree and picks the init frequency
before the devfreq governor starts working. It sets also parent rate (MPLL
to 600MHz).
