Nicolin Chen 9371b7119d drm/tegra: hub: Do not enable orphaned window group ...

[ Upstream commit ef4e417eb3 ]

Though the unconditional enable/disable code is not a final solution,
we don't want to run into a NULL pointer situation when window group
doesn't link to its DC parent if the DC is disabled in Device Tree.

So this patch simply adds a check to make sure that window group has
a valid parent before running into tegra_windowgroup_enable/disable.
