The next change adds DPU_PINGPONG_DSC feature flag to chipsets where it 
is supported. But when I checked there were many chipsets where DSC is 
present but were not added in catalog.

Without doing that, the next change was originally adding 0 to the 
feature flags of those chipsets which didnt seem right to me.

This seemed like the right way to do it to first add the DSC blocks for 
those chipsets and add the feature flag to them in the next change.
