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) Added inbox1 DPIA command subtype DMUB_CMD__DPIA_SET_CONFIG_ACCESS to
issue SET_CONFIG command to DMUB in dc_process_dmub_set_config_async().
DMUB processes the command with DPIA sends reply back immediately or
in an outbox1 message triggering an outbox1 interrupt to driver.
2) DMUB posts SET_CONFIG reply as an Outbox1 message of type
DMUB_OUT_CMD__SET_CONFIG_REPLY.
3) The dmub async to sync mechanism for AUX is modified to accommodate
SET_CONFIG commands for both command issue and reply code paths.
