libata: update ata_dev_try_classify() arguments

Make ata_dev_try_classify() take a pointer to ata_device instead of
ata_port/port_number combination for consistency and add @present
argument.  @present indicates whether the device seems present during
reset.  It's the result of TF access during softreset and link
onlineness during hardreset.  @present will be used to improve
diagnostic failure handling.
