[Why]
DPIA traces from DMUB is not enabled by default, which is
less convenient to debug DPIA related issues because we have
to resort to other debug tools to enable DPIA trace.
[How]
Exposes interfaces to update trace mask from the DMUB GPINT commands.

[why]
There was unfortunately a coding mistake. It gets caught with an ultrawide monitor
that requires ODM 4:1 combine. We are blanking or unblanking pixel data we
are supposed to enumerate through all ODM pipes and program DPG for each
of those pipes. However the coding mistake causes us to program on... | ```diff
