ahci: split ICH and AHCI even more 

Sebastian's patch already did a pretty good job at splitting up ICH-9
AHCI code and the AHCI core. We need some more though. Copyright was missing,
the lspci dump belongs to ICH-9, we don't need the AHCI core to have its
own qdev device duplicate.

So let's split them a bit more in this patch, making things easier to
read an understand.
