Commit 9ce274630495 ("cpufreq: tegra20: Use generic cpufreq-dt driver (Tegra30 supported now)") update the Tegra20 CPUFREQ driver to use the generic CPUFREQ device-tree driver. Since this change CPUFREQ support on the Tegra20 Ventana platform has been broken because the necessary device-tree nodes with the operating point information are not populated for this platform. Fix this by updating device-tree for Venata to include the operating point informration for Tegra20.
