Add validation for the "max-link-speed" DT property in three more
drivers, using the pcie_get_link_speed() helper.
- brcmstb: If the value is missing or invalid, fall back to no
limitation (pcie->gen = 0). Fix the previous incorrect logic.
- mediatek-gen3: If the value is missing or invalid, use the maximum
speed supported by the controller.
- rzg3s-host: If the value is missing or invalid, fall back to Gen2.
This ensures that all users of of_pci_get_max_link_speed() are ready
for the removal of the central range check.
