Subject: drm/v3d: Don't set drm_device->dev_private
Git-commit: af25c16bd1c6e7e73d67271c0fe6e0d5078759f1
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
And switch the helper over to container_of, which is a bunch faster
than chasing a pointer. Plus allows gcc to see through this maze.
