[V2,00/10] cpufreq: Migrate users of policy notifiers to QoS requests

Message

Hello,

Now that cpufreq core supports taking QoS requests for min/max cpu
frequencies, lets migrate rest of the users to using them instead of the
policy notifiers.

The CPUFREQ_NOTIFY and CPUFREQ_ADJUST events of the policy notifiers are
removed as a result, but we have to add CPUFREQ_CREATE_POLICY and
CPUFREQ_REMOVE_POLICY events to it for the acpi stuff specifically,
though they are also used by arch_topology stuff now. So the policy
notifiers aren't completely removed.

Boot tested on my x86 PC and ARM hikey board.

This has already gone through build bot for a few days now.

V1->V2:
- Added Acked-by tags
- Reordered to keep cleanups at the bottom
- Rebased over 5.3-rc1
