[PATCH 18/32] drm/tegra: sor: Hook up I2C-over-AUX to output

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

This is necessary for the output abstraction to retrieve a list of valid
modes from the EDID of a connected panel/monitor. This will be useful in
conjunction with DisplayPort support that will be added in a subsequent
patch, so that the driver can read EDID via the AUX channel.
