ATA / ACPI: remove power dependent device handling
Previously, we wanted SCSI devices corrsponding to ATA devices to be runtime resumed when the power resource for those ATA device was turned on by some other device, so we added the SCSI device to the dependent device list of the ATA device's ACPI node. However, this code has no effect after commit 41863fc (ACPI / power: Drop automaitc resume of power resource dependent devices) and the mechanism it was supposed to implement is regarded as a bad idea now, so drop it.
