I have to clarify in case there was a misunderstanding. When I said
generic-phy I meant drivers/usb/phy/phy-generic.c and I was not
talking about Kishon's new generic PHY framework.

So I was only saying that if the dwc3-pci.c is the only thing that
needs the old usb phy support, then there should not be any problem
dropping the support for it.
