PM: ACPI: reboot: Reinstate S5 for reboot
Commit d60cd06331a3 ("PM: ACPI: reboot: Use S5 for reboot") caused Dell
PowerEdge r440 hangs at reboot.
The issue is fixed by commit 2ca1c94ce0b6 ("tg3: Disable tg3 device on
system reboot to avoid triggering AER"), so use the new sysoff API to
reinstate S5 for reboot on ACPI-based systems.
Using S5 for reboot is default behavior under Windows: "A full shutdown
(S5) occurs when a system restart is requested" [1].
