Thierry Reding f552f95853 drm/tegra: dc: Restore coupling of display controllers ... commit a31500fe7055451ed9043c8fff938dfa6f70ee37 upstream. Coupling of display controllers used to rely on runtime PM to take the companion controller out of reset. Commit fd67e9c6ed ("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.
