ata: libata-core: Fix ata_pci_shutdown_one()
This reverts commit 5b6fba546da246b3d0dd8465c07783e22629cc53.
Commit 5b6fba546da2 ("ata: libata-core: Detach a port devices on
shutdown") modified the function ata_pci_shutdown_one() to stop
(suspend) devices attached to the ports of a PCI AHCI adapter to ensure
that drives are spun down before shutting down a system. However, this
is done only for PCI adapters and not for other types of adapters. This
limitation was addressed with commit 24eca2dce0f8 ("scsi: sd: Introduce
manage_shutdown device flag"). With this, all ATA disks are spun down on
system shutdown, which make the changes introduced with 5b6fba546da2
useless.
