Drop the initial_mode_queried workaround for kms clients which do not
support hotplug, all kms clients should be able to deal with hotplug.

TODO:
-Get a full review from the drm-maintainers on dri-devel done on this driver
--Drop all the logic around initial_mode_queried, the master_set and
- master_drop callbacks and everything related to this. kms clients can handle
- hotplugs.
-Extend this TODO with the results of that review
Please send any patches to Greg Kroah-Hartman <gre...@linuxfoundation.org>,
