Using this patch I can now successfully boot Windows 7 from AHCI using AHCI

ahci: send init d2h fis on fis enable
The drive sends a d2h init fis on initialization. Usually, the guest doesn't
receive fises yet at that point though, so the delivery is deferred.
Let's reflect that by sending the init fis on fis receive enablement.

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.
