Function xhci_cdns3_suspend_quirk is used only in host.c file.
We can make it as static and removes it from host-export.h.

Fix a build warning when USB_CDNS_HOST is not enabled:
In file included from ../drivers/usb/cdns3/core.c:23:0:

static inline int xhci_cdns3_suspend_quirk(struct usb_hcd *hcd)

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 change the functions and objects names in reusable code.
The reusable code includes core.c, core.h, drd.c and drd.h files.
It also changes the names of all references to these functions and
objects in other cdns3 files. There are a lot of changes, but all
changes are very trivial.
The reason of this patch is to avoid of mixing prefix cdns3 and cdnsp in
in cdnsp driver what could introduce some confusion in understanding
of cdnsp driver.
This patch assumes to use three different prefixes in Cadence
USB drivers:
cdns: for common reusable code
cdnsp: for names related only with cdnsp driver
cdns3: for names related only with cdns3 driver

cdns3 has some special PM sequence between xhci_bus_suspend and
xhci_suspend, add quirk to implement it.

The cdns3_host_init() function is declared in host-export.h
but host.c does not include it. Add the include to have
the declaration present (and remove the declaration of
cdns3_host_exit which is now static).
Fixes the following sparse warning:
drivers/usb/cdns3/host.c:58:5: warning: symbol 'cdns3_host_init' was not declared. Should it be static?

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
support for PCIe bus, which is used on FPGA prototyping.
The host side of USBSS-DRD controller is compliant with XHCI
specification, so it works with standard XHCI Linux driver.
