[PATCH 2/2] pci: quirks: Override Synopsys USB 3.x HAPS device driver

[Thinh Nguyen <thinh.nguyen@synopsys.com>]

Synopsys USB 3.x host HAPS platform has a class code of
PCI_CLASS_SERIAL_USB_XHCI, and xhci driver can claim it. However, these
devices should use dwc3-haps driver. Set driver_override to dwc3-haps
for these platforms.
