drm/amd/display: Support for SET_CONFIG processing with DMUB
[Why] To process SET_CONFIG transactions with DMUB using inbox1 and outbox1 mail boxes. [How] 1) DMUB posts SET_CONFIG reply as an Outbox1 message of type DMUB_OUT_CMD__SET_CONFIG_REPLY. 2) The dmub async to sync mechanism for AUX is modified to accommodate SET_CONFIG commands for both command issue and reply code paths.
