Coupling of display controllers used to rely on runtime PM to take the companion controller out of reset. Commit fd67e9c6ed5a ("drm/tegra: Do not implement runtime PM") accidentally broke this when runtime PM was removed.
Restore this functionality by reusing the hierarchical host1x client suspend/resume infrastructure that's similar to runtime PM and which perfectly fits this use-case.
