[PATCH v2 3/5] PCI: tegra264: Use pcie_get_link_speed()

[Hans Zhang <18255117159@163.com>]

Tegra264 was added after pcie_get_link_speed() was introduced and still
indexes pcie_link_speed[] directly.  Convert it to the helper so it does
not depend on the array being exported and cannot go out of bounds on
invalid speed values.
