[PATCH] Make libata not powerdown drivers on PM_EVENT_FREEZE.
At the moment libata doesn't pass pm_message_t down ata_device_suspend. This causes drives to be powered down when we just want a freeze, causing unnecessary wear and tear. This patch gets pm_message_t passed down so that it can be used to determine whether to power down the drive.
