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.
