kernel: kmod-usb-dwc2-pci: Add new package

Add dwc2_pci kernel module into own kernel package.
The dwc2_pci.ko kernel module was always build when kmod-usb-dwc2
was selected, but it was not packaged.

Add the missing kmod-usb-phy-nop dependency to the kmod-usb-dwc2-pci
package too. The CONFIG_USB_DWC2_PLATFORM option is already gone for
some time.
