ata_piix when attached to ICH6M in AHCI mode doesn't provide any benefit over using ahci and has detection problems. Don't let ata_piix claim ICH6M if it's in AHCI mode. This change makes ICH6R the only one which ata_piix can attach to even when it's in ahci mode which is necessary as some devices don't work properly under ahci mode. Drop PIIX_FLAG_AHCI and match the controller directly so that piix_disable_ahci() is called only for it. This change makes PIIX_SCC no longer used and it gets dropped too. This fixes bz 9491.
