PM / devfreq: icc: Add suspend/resume APIs

Browse source 
Absence of traffic is guaranteed when the device sitting behind a devbw
device is suspended. In such cases, it is a waste of power to make non-zero
bandwidth votes or to scale the devbw device. So, provide APIs to
suspend/resume the devbw device as needed.
