Usage of the deprecated binding was added to this dt file with ab9d8032dbd0
("arm64: dts: ls1043a-qds: add mmio based mdio-mux support") in 2022.
At that time the binding had been marked deprecated for years already.
I think it would be good if dtc would warn already if a deprecated
binding is detected, so that CI can complain.
