Revert "leds: handle suspend/resume in heartbeat trigger"

commit 436c4c45b5b9562b59cedbb51b7343ab4a6dd8cc upstream.

This reverts commit 5ab92a7cb82c66bf30685583a38a18538e3807db.

System cannot enter suspend mode because of heartbeat led trigger.
In autosleep_wq, try_to_suspend function will try to enter suspend
mode in specific period. it will get wakeup_count then call pm_notifier
chain callback function and freeze processes.
Heartbeat_pm_notifier is called and it call led_trigger_unregister to
change the trigger of led device to none. It will send uevent message
and the wakeup source count changed. As wakeup_count changed, suspend
will abort.
