It's dead code, the core handles all this directly now.
The only special case is nouveau and tda988x which used one function
for both legacy modeset code and -nv50 atomic world instead of 2
vtables. But amounts to exactly the same.
v2: Rebase over the panel/brideg refactorings in stm/ltdc.

of_device_ids are not supposed to change at runtime. All functions
working with of_device_ids provided by <linux/of.h> work with const
of_device_ids. So mark the non-const structs as const.

drm_debugfs_cleanup() now removes all minor->debugfs_list entries
automatically, so it's not necessary to call
drm_debugfs_remove_files(). Additionally it uses
debugfs_remove_recursive() to clean up the debugfs files, so no need
for adding fake drm_info_node entries.

Instead of linking encoders and bridges in every driver (and getting it
wrong half of the time, as many drivers forget to set the drm_bridge
encoder pointer), do so in core code. The drm_bridge_attach() function
needs the encoder and optional previous bridge to perform that task,
update all the callers.

Make sti driver use register callback to move debugfs
initialization out of sub-components creation.
This will allow to convert driver .load() to
drm_dev_alloc() and drm_dev_register().
sti_compositor bring up 2 crtc but only one debugfs init is
needed so use drm_crtc_index to do it on the first one.
This can't be done in sti_drv because only sti_compositor have
access to the devices.
It is almost the same for sti_encoder which handle multiple
encoder while one only debugfs entry is needed so add a boolean
to avoid multiple debugfs initialization

All outputs have a 1:1 relationship between connectors and encoders
and the driver is relying on the atomic helpers: we can drop the custom
->best_encoder() implementations and let the core call
drm_atomic_helper_best_encoder() for us.

So sti doesn't build because the bridge interfaces changes didn't
catch up to its new DVO driver.
Now I might just carry this patch, but I might just push the
bridge pull into a side-pull until someone resolves it.
So this might not be the right solution to the problem, so
please figure it out and let me know ASAP.
