drm/tegra: Support semi-planar formats on Tegra114+

The NV12, NV21, NV16, NV61, NV24 and NV42 formats are supported by
Tegra114 and later display hardware. Add the necessary programming to
allow them to be used.

Note that this does not work for Tegra186 and later yet because those
generations have a different display architecture that doesn't support
the same formats.
