Subject: [PATCH v4 4/5] scsi: Add PM_EVENT_POWEROFF into suspend callbacks

From: Mario Limonciello <mario.limonciello@....com>

When the ACPI core uses hibernation callbacks for shutdown drivers
will receive PM_EVENT_POWEROFF and should handle it the same as
PM_EVENT_HIBERNATE would have been used.
