This patch adds PPMU (Performance Profiling Monitoring Unit) dt node
Exynos5260 SoC.

Exynos5260 SoC has following PPMU IPs:
- PPMU_DREX0_S0 0x10c60000
- PPMU_DREX0_S1 0x10c70000
- PPMU_DREX1_S0 0x10c80000
- PPMU_DREX1_S1 0x10c90000
- PPMU_EAGLE    0x10cc0000
- PPMU_KFC      0x10cd0000
- PPMU_MFC      0x11040000
- PPMU_G3D      0x11880000
- PPMU_FSYS     0x12220000
- PPMU_ISP      0x13370000
- PPMU_FICM     0x13cb0000
- PPMU_GSCL     0x13e60000
- PPMU_MSCL     0x13ee0000
- PPMU_FIMD0X   0x145b0000
- PPMU_FIMD1X   0x145c0000

The drivers/devfreq/exynos/exynos5_bus.c supports the memory bus frequency/
voltage scaling of Exynos5260 SoC with DEVFREQ framework.
