drm/amd/display: Hook up calls to do stereo mux and dig programming to stereo control interface

[Why]
Implementation of stereo mux register is complete, but unused. Need to
call functions to write relevant configs.

[How]
Add function to write stereo config for enable/disable case and call in
stereo control interface.
