It all depends on how BIOS set up the controller / IO regions during
boot and even worse BIOS might expect certain configuration when ACPI
suspend/resume or shutdown transition is requested. I don't really
think we can include AHCI force-enable in the mainline. It's just too
risky without too much benefit.
