Hi guys,

I've messed up the last send out. Cleanup up some issues reported by people with the accel drivers (duplicated files) and rebased the result.

Apart from that the same approach we already discussed previously.

Please review and comment,
Christian.

Not used by any drivers any more, the only use case in drm_dev_init()
can be inlined now.

We want to remove per minor debugfs directories. Start by stopping
drivers from adding anything inside of those.

Instead of the per minor directories only create a single debugfs
directory for the whole device directly when the device is initialized.

For DRM devices each minor gets a symlink to the per device directory
for now until we can be sure that this isn't useful any more in any way.

Accel devices create only the per device directory and also drops the mid
layer callback to create driver specific files.

v2: cleanup accel component as well

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.

Use managed memory allocation for this. That allows us to not keep
track of all the files any more.
