drm/tegra: Fix reference leak in tegra_dsi_ganged_probe
[ Upstream commit 221e3638feb8bc42143833c9a704fa89b6c366bb ]
The reference taken by 'of_find_device_by_node()' must be released when
not needed anymore. Add put_device() call to fix this.
Fixes: e94236cde4d5 ("drm/tegra: dsi: Add ganged mode support")
