In order for deferred probing to help the device would need to acquire
some resource from the parent USB controller once active, allowing it to
defer when it fails to get that resource.  Currently there's nothing
there for that and it's not clear that's sane and sensible (it'd be more
obvious for it to be a child of the USB controller since that's what it
really is).  

We can't just treat it as a PHY (which is the obvious workaroud) since
we do also need to use the built
in PHY in the SoC.
