Subject: [PATCH v1 37/50] ARM: dts: exynos: change parent and rate of
 bus_fsys in Exynos5422

The FSYS bus OPP table has been aligned to the new parent rate. This patch
sets the proper parent and picks the init frequency before the devfreq
governor starts working. It sets also parent rate (DPLL to 1200MHz).
