[Why & How]
We use outbox interrupt that allows us to do the AUX via DMUB
Therefore, we need to add some irq source related definition
in the header files;
Also, I added debug flag that allows us to turn it on/off
for testing purpose.

Does this completion need to be on the amdgpu device itself?
I would prefer if we keep this as needed within DM itself if possible.

My problem with still leaving this as DC_ENABLE_DMUB_AUX is we shouldn't
require the user to have to flip this on by default later. I think I'd
prefer this still as a DISABLE option if we want to leave it for users
to debug any potential issues.
If there's no value in having end users debug issues by setting this bit
then we should keep it as a dc->debug default in DCN resource.
