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.
