[PATCH 07/13] media: stm32: dcmipp: introduce a dcmipp global media_pipeline

[Alain Volmat]

With the introduction of stm32mp25 containing several capture
devices, it becomes necessary to share the media_pipeline
structure among all capture devices since subdev pads can be
shared between several capture devices.
