all os-api those have post/wait feature will not allowed in pm_callbacks
and pm_handler, until we support by cpu/tcb sched_lock and add
sched_lock/unlock back here. Then should revert this commit.

If sched lock before irq save, and irq handler do post, scheduler will
be delayed after WFI until next sched unlock. which is not acceptable.

pm process should be done by chip specific, but we can provide a standard
flow, then vendor & chip can only focus on handle different state change.
