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.

There is no point in trying to find/allocate the table for every OPP
that is added for a device. It would be far more efficient to allocate
the table only once and pass its pointer to the routines that add the
OPP entry.
Locking is removed from _opp_add_static_v2() and _opp_add_v1() now as
the callers call them with that lock already held.
Call to _remove_opp_table() routine is also removed from _opp_free()
now, as opp_table isn't allocated from within _opp_allocate(). This is
handled by the routines which created the OPP table in the first place.

The OPPs which are never successfully added using _opp_add() are not
required to be freed with the _opp_remove() routine, as a simple kfree()
is enough for them.
Introduce a new light weight routine _opp_free(), which will do that.
That also helps us removing the 'notify' parameter to _opp_remove(),
which isn't required anymore.
Note that _opp_free() contains a call to _remove_opp_table() as the OPP
table might have been added for this very OPP only. The
_remove_opp_table() routine returns quickly if there are more OPPs in
the table. This will be simplified in later patches though.

There are two types of duplicate OPPs that get different behavior from
the core:
A) An earlier OPP is marked 'available' and has same freq/voltages as
the new one.
B) An earlier OPP with same frequency, but is marked 'unavailable' OR
doesn't have same voltages as the new one.
The OPP core returns 0 for the first one, but -EEXIST for the second.
While the OPP core returns 0 for the first case, its callers don't free
the newly allocated OPP structure which isn't used anymore. Fix that by
returning -EBUSY instead of 0, but make the callers return 0 eventually.
As this isn't a critical fix, its not getting marked for stable kernel.
