drm/connector: Allow max possible encoders to attach to a connector
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.
v2: Fixing missed return on amdgpu_dm_connector_to_encoder()
