sched: disable frequency notifications by default
The frequency notifications from the scheduler do not currently respect synchronous topologies. If demand on CPU 0 is driving frequency high and CPU 1 is in the same frequency domain, and demand on CPU 1 is low, frequency notifiers will be continuously sent by CPU 1 in an attempt to have its frequency lowered. Until the notifiers are fixed, disable them by default. They can still be re-enabled at runtime.
