drm/tegra: Changes for v4.12-rc1

This contains various fixes to the host1x driver as well as a plug for a
leak of kernel pointers to userspace.

A fairly big addition this time around is the Video Image Composer (VIC)
support that can be used to accelerate some 2D and image compositing
operations.

Furthermore the driver now supports FB modifiers, so we no longer rely
on a custom IOCTL to set those.

Finally this contains a few preparatory patches for Tegra186 support
which unfortunately didn't quite make it this time, but will hopefully
be ready for v4.13.
