input module. Add it to the allowed properties and augment the existing
nvidia,tegra20-vi example to show a 'vip' property.

We are about to add support for the Tegra20 parallel video capture, which
has no TPG. In preparation for that, limit the VIDEO_TEGRA_TPG option to
Tegra210 which is the only implementation currently provided by this
driver.
