Revert "drm/tegra: gr3d: Convert into dev_pm_domain_attach|detach_list()"

This reverts commit f790b5c09665cab0d51dfcc84832d79d2b1e6c0e.

The reverted commit was not ready to be applied due to dependency on other
OPP/pmdomain changes that didn't make it for the last release cycle. Let's
revert it to fix the behaviour.
