[PATCH 5/6] drm/msm/dpu: simplify dpu_encoder_get_topology() interface

[Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx>]

As a preparation for calling dpu_encoder_get_topology() from different
code paths, simplify its calling interface, obtaining some data pointers
internally instead passing them via arguments.
