I'm afraid I don't understand why this change is needed for all variants 
of DWC3.

Is this needed for socionext dwc3 variant to handle the simple-mfd in 
e.g. arch/arm/dts/uniphier-pxs3.dtsi :

614 usb-glue at 65b00000 {
615     compatible = "socionext,uniphier-pxs3-dwc3-glue",
616              "simple-mfd";
