[PATCH 2/3] drm: atmel_hldc - use generic drm_connector_plug_all() helper

[Alexey Brodkin]

This driver used to have its own implementation of connector_plug_all()
which actually was taken as a prototype of drm_connector_plug_all().

Now when drm_connector_plug_all() exists reusing it here.

And while at it getting rid of mutex in both plug() and unplug()
because they were moved to generic helper as well.
