The card firmware provides a flattened device tree to describe the hardware peripherals on its BARs. This allows U50 driver to load the flattened device tree and generate the device tree node for hardware peripherals underneath. To generate device tree node for U50 card, added PCI quirks to call of_pci_make_dev_node() for U50.
