Subject: [PATCH v2 0/2] PM / devfreq: exynos-ppmu: Add the support of PPMUv2

This patch-set add the support of PPMU ((Platform Performance Monitoring Unit)
version 2.0 which is used on Exynos5433. The exynos-ppmu.c driver supports
both PPMUv1.1 and PPMUv2. This patch-set is testd on Exynos5433-based board.

The SoC list using PPMUv1.1
- Exynos4210/4212/4412, Exynos3250, Exynos5260
The SoC list using PPMUv2
- Exynos5433, Exynos7420

Changes from v1:
(https://lkml.org/lkml/2015/7/22/834)
- Add const keyword to the instance of struct devfreq_event_ops/of_device_id
- Modify the register name of PPMU v2 ('PPMUv2_*' -> 'PPMU_V2_*')
- Reduce the unneed call function of exynos_bus_get_ops()
