Technically, Tegra20 supported HS mode (according to the documentation).
However, from what I have found, it appears that HS mode only works on
Tegra194+ devices. So Thierry suggested that we document that HS is
broken on devices prior to Tegra194.

So the variable 'has_hs_mode_support' is a bit misleading. It might be
better to change this to 'hs_mode_broken' and reverse the logic.
