libata-link: linkify PHY-related functions
Make the following PHY-related functions to deal with ata_link instead
of ata_port.
* sata_print_link_status()
* sata_down_spd_limit()
* ata_set_sata_spd_limit() and friends
* sata_link_debounce/resume()
* sata_scr_valid/read/write/write_flush()
* ata_link_on/offline()
This patch introduces no behavior change.
