drm/tegra: dsi - Implement VDD supply support
The DSI controllers are powered by a (typically 1.2V) regulator. Usually this is always on, so there was no need to support enabling or disabling it thus far. But in order not to consume any power when DSI is inactive, give the driver a chance to enable or disable the supply as needed. Signed-off-by: Thierry Reding <treding@nvidia.com>
