[PATCH RFC v3 34/41] pm8001: use libsas-provided domain devices for SATA

[Hannes Reinecke <hare@xxxxxxx>]

The pm8001 driver assumes that libsas does not provide any domain
devices for SATA, which is actually not true.
So use the libsas-provided domain devices for SATA and don't
allocate private ones.
