drm/debugfs: remove dev->debugfs_list and debugfs_mutex v2
The mutex was completely pointless in the first place since any
parallel adding of files to this list would result in random
behavior since the list is filled and consumed multiple times.
Completely drop that approach and just create the files directly but
return -ENODEV while opening the file when the minors are not
registered yet.
v2: rebase on debugfs directory rework, limit access before minors are
registered.
