usb: dwc3: core: fix ordering for PHY suspend

Browse Source 
commit dc99f16f07 upstream.

We can't suspend the PHYs before dwc3_core_exit_mode()
has been called, that's because the host and/or device
sides might still need to communicate with the far end
link partner.

Fixes: 8ba007a (usb: dwc3: core: enable the USB2 and USB3 phy in probe)
