We are now able to configure a pipeline directly into a local display
list body. Take advantage of this fact, and create a cacheable body to
store the configuration of the pipeline in the pipeline object.
vsp1_video_pipeline_run() is now the last user of the pipe->dl object.
Convert this function to use the cached pipe->stream_config body and
obtain a local display list reference.
Attach the pipe->stream_config body to the display list when needed
before committing to hardware.
Use a flag 'configured' to know when we should attach our stream_config
to the next outgoing display list to reconfigure the hardware in the
event of our first frame, or the first frame following a suspend/resume
cycle.
Our video DL usage now looks like the below output:
dl->body0 contains our disposable runtime configuration. Max 41.
dl_child->body0 is our partition specific configuration. Max 12.
dl->bodies shows our constant configuration and LUTs.
These two are LUT/CLU:
* dl->bodies[x]->num_entries 256 / max 256
* dl->bodies[x]->num_entries 4914 / max 4914
Which shows that our 'constant' configuration cache is currently
utilised to a maximum of 64 entries.
