Convert the ST AHCI SATA Controller to DT schema format. The phy-names changes from "ahci_phy" to "sata-phy" with the inclusion of ahci-common.yaml. That's an ABI change, but the Linux driver at least ignores the names. The binding uses "ports-implemented" property, so including ahci-common.yaml is required.
