Add the delayed timer to devfreq framework in order to support
the periodical polling mode without stop caused by CPU idle state.
Some Non-CPU device must need to monitor the device status like
utilization regardless of CPU state.

- patch1 explains the detailed reason why the delayed timer is required.
- patch2 initializes that exynos5422-dmc device use delayed timer as default
instead of deferrable timer.
