Subject: [PATCH] dt-bindings: usb: dwc3-imx8mp: dma-range is required only for imx8mp
Only i.MX8MP need dma-range property to let USB controller work properly.
Remove dma-range from required list and add limitation for imx8mp.
Fixes: d2a704e29711 ("dt-bindings: usb: dwc3-imx8mp: add imx8mp dwc3 glue bindings")
