Subject: usb: dwc3: core: fix ordering for PHY suspend
From: Felipe Balbi <balbi@xxxxxx>
commit dc99f16f076559235c92d3eb66d03d1310faea08 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)
