PCI: dwc: Use pcie_get_link_speed() helper for safe array access
Replace direct indexing of pcie_link_speed[] with the new helper
pcie_get_link_speed() in all DesignWare core and glue drivers. This
ensures that out-of-range generation numbers do not cause out-of-bounds
accesses when the helper returns PCI_SPEED_UNKNOWN, and prepares for
the removal of the range check in of_pci_get_max_link_speed().
The actual validation of the "max-link-speed" DT property (e.g., fallback
to a safe default and warning) is added in subsequent patches for each
driver that reads the property.
