Add AHCI PCI bindings for Marvell 88SE6121/45 SATA controllers. The 88SE6121 controller is used, for example, in the Seagate Blackarmor NAS440 or the Iomega ix4-200d NAS. As Pali Rohár explained [1], these controllers do not match the standard AHCI class code and therefore require an explizit PCI binding. The Linux kernel also uses this approach [2].
