ARM: dts: Add the support for exynos busfreq on Exynos3250-based Rinato/Monk board
This patch adds the Exynos3250 memory-bus node which includes the regulator
and devfreq-event phandle. The devfreq-event phandle is used for the
governor of devfreq device and provide the current usage state of
MIF (Memory Interface) / INT (Internal) memory bus group.
