Currently, the ata_port print_ids are increased indefinitely, even when
there are lower ids available.

E.g. on first boot you will have ata1-ata6 assigned.
After a rmmod + modprobe, you will instead have ata7-ata12 assigned.

Move to use the ida_alloc() API, such that print_ids will get reused.
This means that even after a rmmod + modprobe, the ports will be assigned
print_ids ata1-ata6.
