I can't seem to figure out how to connect a generic phy device
to the usb UDC logic, as the dwc2 code seems to exclusively work
with either generic phys or usb-phys.
So to try to make this work with the phy-hi6220-usb driver, tweak
the dwc2 logic to support call hooks to both phy and uphy devices.
I realize this is likely wrong, but without a good pointer as to
how this should be done, I'm a bit wandering around in the dark.
