Right, even if we do a local enqueue from higher base timer into lower base we

I thought I can skip initialization because I update base->next
in the interrupt or in __remove_hrtimer, like:
- enqueue_timer, base->next is 0
- reprogram device

The sequence is as follows:
- CPU enters idle, we disable tick
- hrtimer interrupt fires (for hrtimer_wakeup)
- for clock base #1 (REALTIME) we wake up SCHED_RT thread and
start RT period timer (from start_rt_bandwidth) for clo
