arm64: dts: imx95: switch usb3 controller to flattened model

Browse Source 
Switch to use flattened model for USB3 controller. To enable USB
controller with restricted DMA access range to work correctly, add a
simple-bus to constrain the dma address.

Note:
  This changes the USB controller compatible string from "fsl,imx95-dwc3"
  to "nxp,imx95-dwc3". This requires a kernel with CONFIG_USB_DWC3_IMX
  enabled; otherwise, the new DTB will not be compatible with older one.
  As i.MX95 is a new SoC and is still under development, it's acceptable
  at development early phase.
