VIP is the parallel video capture component within the video input
subsystem of Tegra20 (and other Tegra chips, apparently).

Signed-off-by: Luca Ceresoli <luca.ceresoli@bootlin.com>

---

Changed in v2 (suggested by Krzysztof Kozlowski):
- remove redundant "bindings" from subject line
- remove $nodename
- add channel@0 description
- add reg: const: 0
