The DRM pipelines don't partition frames, as the hardware operates synchronously with the display. 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.
