[RFC PATCH 3/5] ARM: dts: Add PPMU dt node for Exynos3250

[Chanwoo Choi]

This patch add PPMU (Performance Profiling Monitoring Units) dt node
to estimate the utilization of each IP in Exynos SoC throught DEVFREQ Event
subsystem.

This patch adds following PPMU dt nodes:
- PPMU_DMC0	0x106a0000
- PPMU_DMC1	0x106b0000
- PPMU_RIGHTBUS 0x112A0000
- PPMU_LEFTBUS  0x116A0000
- PPMU_CAMIF    0x11AC0000
- PPMU_LCD0     0x11E40000
- PPMU_3D       0x13220000
- PPMU_MFC_L    0x13660000
- PPMU_CPU	0x106c0000
