[PATCH] PCI: brcmstb: Assign pcie->gen from pcie_get_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().
