I thought about that too, but it will end up with ata1-6 with dummy 3
and 4 while the BIOS shows continuous 4 ports. I wanted avoid this
discrepancy as it could cause confusion to users.

The other option is adding pp->port_idx to record hw port index. It
does make the code a bit simpler. What do you think about this?

Thanks.
