Reuse ata_port_{suspend|resume}_common for sas. This path is chosen over adding coordination between ata-tranport and sas-transport because libsas wants to revalidate the domain at resume-time at the host level. It can not validate links have resumed properly until libata has had a chance to perform its revalidation, and any sane placing of an ata_port in the sas-transport model would delay it's resumption until after the host.Export the common portion of port suspend/resume (bypass pm_runtime), and allow sas to perform these operations asynchronously (similar to the libsas async-ata probe implmentation). Async operation is determined by having an external, rather than stack based, location for storing the result of the operation.
