From: Dhinakaran Pandiyan <dhinakaran.pandiyan@xxxxxxxxx>
Currently we restrict the number of encoders that can be linked to
a connector to 3, increase it to match the maximum number of encoders
that can be initialized(32).
To more effiently do that lets switch from an array of encoder ids to
bitmask.
Also removing the best_encoder hook from the drivers that only have
one encoder per connector(this ones have one encoder in the whole
driver), pick_single_encoder_for_connector() will do the same job
with no functional change.
v2: Fixing missed return on amdgpu_dm_connector_to_encoder()
