[PATCH] Suspend support for libata
This patch adds suspend patch to libata, and ata_piix in particular. For most low level drivers, they should just need to add the 4 hooks to work. As I can only test ata_piix, I didn't enable it for more though. Suspend support is the single most important feature on a notebook, and most new notebooks have sata drives. It's quite embarrassing that we _still_ do not support this. Right now, it's perfectly possible to suspend the drive in mid-transfer.
