This patchset support devicetree and use common ppmu driver instead of
individual code of exynos4_bus.c to remove duplicate code. Also this patchset
get the resources for busfreq from dt data by using DT helper function.
- PPMU register address
- PPMU clock
- Regulator for INT/MIF block

This patchset use SET_SYSTEM_SLEEP_PM_OPS macro intead of legacy method.
To remove power-leakage in suspend state, before entering suspend state,
disable ppmu clocks.
