drm/tegra: Changes for v4.5-rc1

This adds support for the version of host1x found on Tegra210 SoCs. It
also makes use of the new atomic suspend/resume functionality to bring
this feature to Tegra.

Other than that it's mostly small fixes and cleanups, with some prep-
work for things that will hopefully get merged for the next release.
