libata-link: make two port flags HRST_TO_RESUME and SKIP_D2H_BSY link flags
HRST_TO_RESUME and SKIP_D2H_BSY are link attributes. Move them to ata_link->flags. This will allow host and PMP links to have different attributes. ata_port_info->link_flags is added and used by LLDs to specify these flags during initialization.
