[PATCH v2 9/9] drm/tegra: Run hub cleanup on ->remove()

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

The call to tegra_display_hub_cleanup() that takes care of disabling the
window groups is missing from the driver's ->remove() callback. Call it
to make sure the runtime PM reference counts for the display controllers
are balanced.
