Frederic Weisbecker bb0c250e8e timers/migration: Temporarily disable per capacity hierarchies ...

Some workloads with different CPU capacities consume more power with
timer migration than before. The recently introduced per capacity
hierarchies were supposed to alleviate this problem. However it appears
to also regress other types of workloads, especially when plenty of
capacities live together in the same machine.

Disable the feature until a reasonable solution is found.
