Two commits which made their way into Linux stable broke the SATA support on the BPi-R64. Fix this by reverting a node rename which broke DT-overlay application and import a (still pending) patch re-adding the 'syscon' compatible to the pciesys clock-controller which also contains phy-mode bits referenced by the ahci_mtk driver expecting to access them using syscon_regmap_lookup_by_phandle().
