ARM: tegra: Enable eDP for Venice2
Venice2 has a 12.9" (2560x1700) panel connected to the eDP output of the Tegra124. The panel has an EDID to describe the video timings but needs a few extra nodes to get the backlight to come up. Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>
