Subject[PATCH 0/3 v6] drm: Introduce drm_connector_register_all() helper
As a pair to already existing drm_connector_unplug_all()
(which we'll rename in this series to drm_connector_unregister_all())
we're adding generic implementation of what is already done in some drivers
for registering all connectors.

After implementation of that new helper we're updating 2 drivers
that used to use it's own implementation:
[1] atmel_hlcdc
[2] rcar_du

Other drivers still use load() callback and so should be first modified so
their load() gets called from their probe() explicitly.

Build- and run-tested on yet to be upstreamed ARC PGU (part of AXS10x board).

Changes v5 -> v6:
* In atmel_hlcdc only substitute its own atmel_hlcdc_dc_connector_plug_all().
drm_connector_unregister_all() is already used there since
222b90943446 "drm/atmel: Fixup drm_connector_/unplug/unregister/_all"

Changes v4 -> v5:
* Added missing mutex unlock on a fail path in drm_connector_register_all()
Thanks David for his attention and patience!

Changes v3 -> v4:
* Based on current drm-intel/topic/drm-misc
It's now on commit 6c87e5c3ec6db052f3744804a517b6fb003906e1
And since thet new base already has
"drm: Rename drm_connector_unplug_all() to drm_connector_unregister_all()"
this series now only includes 3 subsequent patches.

* In drm_connector_register_all() fail path which calls unregister_all()
is moved outside of loop&locked section (as suggested by Daniel)

Changes v2 -> v3:
* Added acks for 1, 3 and 4 patches
* Updated kerneldoc descriptins of both register_ and unregister_all()
* Updated commit messages (mostly spellos and grammar issues)

Changes v1 -> v2:
* Rename drm_connector_unplug_all() to drm_connector_unregister_all()
* Use drm_for_each_connector() instead of list_for_each_entry()
* Updated kerneldoc for drm_dev_register()
