Whether a controller needs IDE or SATA ACPI hierarchy is determined by the programming interface of the controller not by whether the controller is SATA or PATA, or it supports slave device or not. This patch adds ATA_FLAG_ACPI_SATA port flags which tells libata-acpi that the port needs SATA ACPI nodes, and sets the flag for ahci and sata_sil24.

I don't think the situation is as static as a compiled-in driver flag implies. And I'm not really convinced a driver flag is needed, or wanted.
If anything, the only flag we /may/ need could be a ATA_FLAG_NEVER_EVER_DO_ACPI_FOR_THIS_CONTROLLER.
