Support both the HSV24 and HSV32 formats. From a hardware point of view
pretend the formats are RGB, the RPF and WPF will just pass the data
through without performing any processing.

The VYUY format isn't supported on Gen3 hardware, disable it.
Gen2 hardware supports VYUY in practice even though the documentation
doesn't advertise it, so keep it for Gen2 devices.

We don't need to walk the pipeline when propagating the alpha value as
all the information needed for propagation is already available from the
pipeline structure.

The vsp1_pipeline_reset() function loops over pipeline inputs and output
and resets them. When doing so it assumes both that the pipeline has
been correctly configured with an output, and that inputs are are stored
in the pipe inputs array at positions 0 to num_inputs-1.
Both the assumptions are incorrect. The pipeline might need to be reset
after a failed attempts to configure it, without any output specified.
Furthermore, inputs are stored in a positiong equal to their RPF index,
possibly creating holes in the inputs array if the RPFs are not used in
sequence.
Fix both issues by looping over the whole inputs array and skipping
unused entries, and ignoring the output when not set.

Instead of embedding pipelines in the vsp1_video objects allocate them
on demand when they are needed. This fixes the streamon race condition
where pipelines objects from different video nodes could be used for the
same pipeline.

This prepares for dynamic pipeline allocation by providing a field that

The subdev s_stream operation is abused as a generic way to setup
modules at every frame. Move the code out to a new VSP1 entity configure
operation.
Most modules now have an empty s_stream operation that can be removed.
The only exception is the WPF module that needs to perform hardware
configuration when stopping the stream. The code can be simplified
accordingly as we know that that operation never fails.

The function can only be called from a s_stream handler as it requires a
valid display list context (due to calling vsp1_uds_set_alpha() which
writes to module registers). Document the requirement.

The DRM pipeline, as it runs in automatic restart mode, never sees the
pipeline state set to VSP1_PIPELINE_STOPPING or VSP1_PIPELINE_STOPPED
when running the frame end interrupt handler. We can thus skip the
checks various checks in the handler and return immediately.
Similarly the DRM frame end handler calls vsp1_pipeline_run()
unnecessarily, as the state there is never VSP1_PIPELINE_STOPPED. Remove
the function call and the frame end handler is it's now empty.

Display lists contain lists of registers and associated values to be
applied atomically by the hardware. They lower the pressure on interrupt
processing delays when reprogramming the device as settings can be
prepared well in advance and queued to the hardware without waiting for
the end of the current frame.
Display list support is currently limited to the DRM pipeline.

The pipeline inputs array stores pointers to all RPFs contained in the
pipeline. It's currently indexed contiguously by adding RPFs in the
order they are found during graph walk. This can't easily support
dynamic addition and removal of RPFs while streaming, which will be
required for combined VSP+DU support.
Make the array indexed by RPF index instead and skip NULL elements when
iterating over RPFs.
