drm/amd/display: Acquire DSC during split stream for ODM only if top_pipe
[WHY] DSC should only be acquired per OPP. Therefore, DSC should only be acquired for the top_pipe when ODM is enabled. Not doing this check may lead to acquiring more DSC's than needed when doing MPO + ODM Combine. [HOW] Only acquire DSC if pipe is top_pipe.
