cpuidle: redirect some hpet lock users to a new cpumask_lock

The hpet channel lock was also used for prevent handle_hpet_broadcast
access other cpu's timer_deadline_start/end after other cpu was
already waken up.
This purpose can be approached via a standalone lock to remove much
spins on the hpet channel lock.
