Integrate ata objects [port, link, device] with scsi objects.
Before [2.6.x]
The path of a scsi device is:
.../0000:00:1f.2/host0/port1/link1/dev1.0/target0:0:0/0:0:0:0
or when a port multiplier is present: for instance the device in port 4 of the
port multiplier:
.../0000:00:06.0/0000:09:00.0/host5/port6/link6.4/dev6.4.0/target5:4:0/5:4:0:0
Fix ACPI code that relied on previous topology.
