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'
Issue occurs for USB/CDNS3/CDNSP kernel configuration:
CONFIG_USB=m
CONFIG_USB_CDNS_SUPPORT=y
CONFIG_USB_CDNS3=m
CONFIG_USB_CDNS3_PCI_WRAP=m
CONFIG_USB_CDNSP_PCI=y

Patch fixes the following compilation error:
ld: drivers/usb/cdns3/host.o: in function `xhci_cdns3_suspend_quirk':
host.c:(.text+0x9): undefined reference to `usb_hcd_is_primary_hcd'
This reference to 'usb_hdc_is_primary_hcd' is from hcd_to_xhci(),
which is being built as a loadable module:
int xhci_cdns3_suspend_quirk(struct usb_hcd *hcd)
{
struct xhci_hcd *xhci = hcd_to_xhci(hcd);
Issue occurrd for following kernel configuration:
CONFIG_USB_GADGET=y
CONFIG_USB_SUPPORT=y
CONFIG_USB_COMMON=y
CONFIG_USB_ARCH_HAS_HCD=y
CONFIG_USB=m
CONFIG_USB_CDNS_SUPPORT=y
CONFIG_USB_CDNS_HOST=y
CONFIG_USB_CDNS3=m

This patch introduces the main part of Cadence USBSSP DRD driver
to Linux kernel.
To reduce the patch size a little bit, the header file gadget.h was
intentionally added as separate patch.
The Cadence USBSSP DRD Controller is a highly configurable IP Core which
can be instantiated as Dual-Role Device (DRD), Peripheral Only and
Host Only (XHCI)configurations.
The current driver has been validated with FPGA platform. We have
support for PCIe bus, which is used on FPGA prototyping.
The host side of USBSS DRD controller is compliant with XHCI.
The architecture for device side is almost the same as for host side,
and most of the XHCI specification can be used to understand how
this controller operates.

Patch moves common reusable code used by cdns3 and cdnsp driver
to cdns-usb-common library. This library include core.c, drd.c
and host.c files.

Patch splits file core.c into core.c containing the common reusable code
and cnd3-plat.c containing device platform specific code. These changes
are required to make possible reuse DRD part of CDNS3 driver in CDNSP
driver.

This patch introduce new Cadence USBSS DRD driver to Linux kernel.
The Cadence USBSS DRD Controller is a highly configurable IP Core which
can be instantiated as Dual-Role Device (DRD), Peripheral Only and
Host Only (XHCI)configurations.
The current driver has been validated with FPGA platform. We have

The host side of USBSS-DRD controller is compliant with XHCI
specification, so it works with standard XHCI Linux driver.
