[media] v4l: vsp1: wpf: Clear RPF to WPF association at stream off time
The VSP1 stores the video pipelines' input (RPF) to output (WPF)
mappings in a WPF register. An RPF must never be associated with
multiple WPFs, even if all of those WPFs but one are unused, otherwise
the hardware won't function properly.
The driver doesn't ensure this correctly as it never clears the
mappings. An RPF used with one WPF and later with a different WPF will
lead to malfunction, as it will be associated with two WPFs. Clear the
mappings at stream off time to fix this.

[media] v4l: vsp1: wpf: Simplify cast to pipeline structure

casting from the subdev to the wpf object and back to the subdev.

[media] v4l: vsp1: Cleanup video nodes at removal time
Video nodes created and initialized in the RPF and WPF init code paths
are never unregistered, and the related resources (videobuf alloc
context and media entity) never released.
Fix this by storing a pointer to the vsp1_video object in vsp1_entity
and calling vsp1_video_cleanup() from vsp1_entity_destroy(). This also
allows simplifying the init error code paths.

[media] v4l: Renesas R-Car VSP1 driver
The VSP1 is a video processing engine that includes a blender, scalers,
filters and statistics computation. Configurable data path routing logic
allows ordering the internal blocks in a flexible way.
Due to the configurable nature of the pipeline the driver implements the
media controller API and doesn't use the V4L2 mem-to-mem framework, even
though the device usually operates in memory to memory mode.
Only the read pixel formatters, up/down scalers, write pixel formatters
and LCDC interface are supported at this stage.
