cpufreq: Implement cpufreq_generic_suspend()
[ Upstream commit e28867eab7c0a60cddf0cb59f9f6cbbd9561425d ]
Multiple platforms need to set CPU to a particular frequency before suspending
system. And so they need a common infrastructure which is provided by this
patch. Those platforms just need to initialize their ->suspend() pointers with
the generic routine.
