Subject: ARM: dts: exynos: Add DMC bus frequency for exynos3250-rinato/monk

This patch adds the DMC (Dynamic Memory Controller) bus frequency node
which includes the devfreq-events and regulator properties. The bus
frequency support the DVFS (Dynamic Voltage Frequency Scaling) feature
with ondemand governor.

The devfreq-events (ppmu_dmc0*) can monitor the utilization of DMC bus
on runtime and the buck1_reg (VDD_MIF power line) supplies the power to
the DMC block.

Subject: ARM: dts: exynos: Add exynos4412-ppmu-common dtsi to delete duplicate
 PPMU nodes

This patch adds the exynos4412-ppmu-common.dtsi to remove duplicate PPMU nodes
because exynos3250-rinato/monk, exynos4412-trats2/odroidu3 has the same
PPMU device tree node.
