Subject: [PATCH v1 41/50] ARM: dts: exynos: change parent and rate of
 bus_g2d in Exynos5422

The bus_g2d 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 (MPLL to 600MHz).
