drm/tegra: Fixes for v4.16-rc7

This contains two small fixes for the alpha blending support that was
merged into v4.16-rc1 and a fix for connector reference leaks caused by
the fact that display pipelines are no longer automatically disabled if
the framebuffer is removed.

Furthermore this contains a fix for a crash on IOMMU detach at driver
unbind time and a regulator enable/disable unbalance fix.
