usb: cdnsp: fixes undefined reference to cdns_remove

Patch fixes the following errors:
ld: drivers/usb/cdns3/cdnsp-pci.o: in function `cdnsp_pci_remove':
cdnsp-pci.c:(.text+0x80): undefined reference to `cdns_remove'
ld: drivers/usb/cdns3/cdnsp-pci.o: in function `cdnsp_pci_probe':
cdnsp-pci.c:(.text+0x34c): undefined reference to `cdns_init'

CONFIG_USB_CDNS3=m
CONFIG_USB_CDNS3_PCI_WRAP=m
