The entity operations access configuration data from the entity state in that case, instead of accessing the partition structure. This requires special cases in entity-specific code, increasing the driver complexity. To prepare for simplifying the code, initialize a single partition for the DRM pipelines, similarly to how video pipelines create one partition spanning the full image when partitioning isn't needed. The partition is allocated statically in the vsp1_drm_pipeline structure instead of dynamically as for video pipelines, as DRM pipelines are guaranteed to operate on a single partition.
