1272fd652a usb: cdns3: Fix issue with using incorrect PCI device function 
PCI based platform can have more than two PCI functions.
USBSS PCI Glue driver during initialization should
consider only DRD/HOST/DEVICE PCI functions and
all other should be ignored. This patch adds additional
condition which causes that only DRD and HOST/DEVICE
function will be accepted.

7733f6c32e usb: cdns3: Add Cadence USB3 DRD 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
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.
