ARM: tegra: Populate OPP table for Tegra20 Ventana

Browse Source 
commit bd7cd7e05a42491469ca19861da44abc3168cf5f upstream.

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.
