Subject: [PATCH v1 28/50] ARM: dts: exynos: change OPPs for g2d and g2d_acp
 buses in Exynos5420

Align the frequencies in OPPs to values which are possible to set using
a divider and parent clock rate. Keep the OPP number in the table equal
or less to the number in bus_wcore (any higher OPPs would not be set).
