We found a compilation error that we thought was caused by the 3DLUT
patch; later on, we figured out the root cause of the problem, but we
already applied the revert in the wrong patch. This commit brings it
back  the 3DLUT fix.

[Why]
Created new fields that matches new B0 structs On DCN31 the mapping of
DIO output to PHY differs from A0 to B0 boards with new PHY C20 & this
new mapping needed to be handled.

[How]
Mapped new structure based on new structs Added logic for mapping over
A0 and B0 boards Hooked all new structs together.

[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.
