Fix ThinkPad T42 poweroff failure introduced by by "PM: Introduce pm_power_off_prepare"

Commit bd804eba1c8597cbb7cd5a5f9fe886aae16a079a ("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.
