drm/amd/display: Enable ODM combine default policy

[Why&How]
Output Data Mapping is a power saving feature that allows us to run at
reduced DPP and DISP clocks compared to what could be achieved with a
single pipe.

Set the default policy for single display use case to use 2 to 1 ODM combine.
The options are queried by DC and appropriate register programming sequence
is initiated to enable this feature.
