Subject: [PATCH v1 38/50] ARM: dts: exynos: change parent and rate of
 bus_fsys2 in Exynos5422

The FSYS2 bus OPP table has been aligned to the new parent rate.  The OPP
table is also shared with bus_fsys. 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).
