i.MX95 DWC3 inside HSIOMIX could still wakeup Linux, even if HSIOMIX
power domain(Digital logic) is off. There is still always on logic
have the wakeup capability which is out band wakeup capbility.

So use device_set_out_band_wakeup for i.MX95 to make sure DWC3 could
wakeup system even if HSIOMIX power domain is in off state.
