libata-link: introduce ata_link
Introduce ata_link. It abstracts PHY and sits between ata_port and ata_device. This new level of abstraction is necessary to support SATA Port Multiplier, which basically adds a bunch of links (PHYs) to a ATA host port. Fields related to command execution, spd_limit and EH are per-link and thus moved to ata_link. This patch only defines the host link. Multiple link handling will be added later. Also, a lot of ap->link derefences are added but many of them will be removed as each part is converted to deal directly with ata_link instead of ata_port. This patch introduces no behavior change.
