This sets ground for adding suspend/resume events.
The devfreq apis are not modified and are kept intact.

Add devfreq suspend/resume apis for devfreq users. This patch
supports suspend and resume of devfreq load monitoring, required
for devices which can idle.

ften. However, it may behave incorrectly.

Plus, please edit Documentation/ABI entry (central_polling is being
removed)
Done.
Other than that, it looks fine.

Devfreq returns governor predicted frequency as current frequency
via sysfs interface. But device may not support all frequencies
that governor predicts. So add a callback in device profile to get
current freq from driver. Also add a new sysfs node to expose
governor
