No need to.
Also, as the CDM block seems to be common to all existing platforms,
what about moving this definition to dpu_hw_catalog.c next to VBIF
settings?
Thanks for the feedback and sorry for the delay in getting back to this

Ack. Yes lets move it to dpu_hw_catalog.c and remove explicit 0
assignment for features.
