libata-link: implement and use link/device iterators
Multiple links and different number of devices per link should be
considered to iterate over links and devices. This patch implements
and uses link and device iterators - ata_port_for_each_link() and
ata_link_for_each_dev() - and ata_link_max_devices().
This change makes a lot of functions iterate over only possible
devices instead of from dev 0 to dev ATA_MAX_DEVICES. All such
changes have been examined and nothing should be broken.
While at it, add a separating comment before device helpers to
distinguish them better from link helpers and others.
