usb: dwc3: fix PHY disable sequence
commit d2ac7bef95c9ead307801ccb6cb6dfbeb14247bf upstream.
Generic PHYs must be powered-off before they can be tore down.
Similarly, suspending legacy PHYs after having powered them off makes no
sense.
Fix the dwc3_core_exit() (e.g. called during suspend) and open-coded
dwc3_probe() error-path sequences that got this wrong.
Note that this makes dwc3_core_exit() match the dwc3_core_init() error
path with respect to powering off the PHYs.
Fixes: 03c1fd622f72 ("usb: dwc3: core: add phy cleanup for probe error handling")
Fixes: c499ff71ff2a ("usb: dwc3: core: re-factor init and exit paths")
