usb: dwc2: pci: Correctly compile dwc2-pci as a module or built-in

Browse Source 
The dwc2-pci driver should be compiled as a module when configured to
do so. If the dwc2-pci is configured as a module but actually
built-in, it can cause build errors due to the fact that the
generic-phy will be allowed to compile as a module causing undefined
references.
