scsi: sd: Add manage_restart device attribute to scsi_disk
In addition to the already existing manage_shutdown,
manage_system_start_stop and manage_runtime_start_stop device scsi_disk
attributes, add manage_restart, which allows the high-level device
driver (sd) to manage the device power state for SYSTEM_RESTART if set
to 1.
This attribute is necessary for the following commit "ata: stop disk on
restart if ACPI power resources are found" to avoid a potential disk
power failure in the case the SATA power connector does not retain the
power state after a restart.
