usb: musb: sunxi: Fix accessing an released usb phy
Commit 6ed05c68cbca ("usb: musb: sunxi: Explicitly release USB PHY on exit") will cause that usb phy @glue->xceiv is accessed after released.
1) register platform driver @sunximusbdriver // get the usb phy @glue->xceiv sunximusbprobe() -> devmusbget_phy().
2) register and unregister platform driver @musbdriver musbprobe() -> sunximusbinit() use the phy here //the phy is released here musbremove() -> sunximusbexit() -> devmusbputphy()
3) register @musbdriver again musbprobe() -> sunximusbinit() use the phy here but the phy has been released at 2). ...
Fixed by reverting the commit, namely, removing devmusbputphy() from sunximusb_exit().
