Commit bd804eba1c ("PM: Introduce
pm_power_off_prepare") caused problems in the poweroff path, as reported by
YOSHIFUJI Hideaki / 吉藤英明.
Generally, sysdev_shutdown() should be called after the ACPI preparation for
powering the system off. To make it happen, we can separate sysdev_shutdown()
from device_shutdown() and call it directly wherever necessary.
