This patch adds PPMU (Platform Performance Monitoring Unit) Device-tree node
to measure the utilization of each IP in Exynos SoC.
- PPMU_D{0|1}_CPU are used to measure the utilization of MIF (Memory Interface)
block with VDD_MIF power source.
- PPMU_D{0|1}_GENERAL are used to measure the utilization of INT(Internal)
block with VDD_INT power source.
