PCI: brcmstb: Assign pcie->gen from of_pci_get_max_link_speed()
After commit 03f920936977 ("PCI: controller: Validate max-link-speed"),
pcie->gen stopped being assigned and as a result the established PCIe link
would stop supporting Gen3 speeds on 2712 since pcie->gen is used to
populate LnkCntl2 and LnkCap in brcm_pcie_set_gen().
If the 'max-link-speed' property is not specified, or it exceeds Gen3,
resort to the HW defaults.
