Declare a fixup quirk. I'm not a pci expert, but I think something
like this should work..
static void dwc3_fix_amd_nl_class(struct pci_dev *pdev)
{
pdev->class = 0x0c03fe;
}
DECLARE_PCI_FIXUP_HEADER(PCI_VENDOR_ID_AMD, PCI_DEVICE_ID_AMD_NL,
dwc3_fix_amd_nl_class);

The DWC3 is not given xHCI class code on our boards.
