drm/amd/display: implement force function in amdgpu_dm_connector_funcs

Browse source 
[Why]
When userspace (IGT) inserts EDID with audio data (ELD), EDID
is not updated.

[How]
Implements force function (amdgpu_dm_connector_funcs_force) in
amdgpu_dm_connector_funcs to create emulated sink and to handle
EDID.
