DPU < 7.0.0 has DPU_PINGPONG_DSC feature bit set to indicate it requires
both dpu_hw_pp_setup_dsc() and dpu_hw_pp_dsc_{enable,disable}() to be
executed to complete DSC configuration if DSC hardware block is present.
Hence test DPU_PINGPONG_DSC feature bit and assign DSC related functions
to the ops of PINGPONG block accordingly if DPU_PINGPONG_DSC bit is set.

changes in v6:
-- split patches and keep the function file handles DPU_PINGPONG_DSC bit at this patch

Please correct me if I'm wrong, the overall suggestion was to have 
actual catalog changes before this patch. However I do not see this 
feature bit being enabled at all!
