ata: libata-core: Do not register PM operations for SAS ports
libsas does its own domain based power management of ports. For such ports, libata should not use a device type defining power management operations as executing these operations for suspend/resume in addition to libsas calls to ata_sas_port_suspend() and ata_sas_port_resume() is not necessary (and likely dangerous to do, even though problems are not seen currently). Introduce the new ata_port_sas_type device_type for ports managed by libsas. This new device type is used in ata_tport_add() and is defined without power management operations.
