A commit which made their way into Linux stable down to 5.15 broke the
SATA support on the BPi-R64.
Fix this by importing 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().
