[v5,0/2] upon streaming, check that the pipeline starts with a source entity

Message

The first patch in this patchset moves the dev field of each
entity struct to the common struct vimc_ent_device.

The second patch fixes a crashing bug when the pipeline does not start with a
source entity.

Fixes from v4:

- NO changes in the first patch since v4

- The function vimc_streamer_pipeline_init now gets the media_entity
as parameter and I changed the while loop to "while(ent)" since this the
valid behaviour: loop until the source of the pipeline.
All other cases should return from the while loop with "goto err".
Also, after calling v4l2_subdev_call, if  'ret' is ENOIOCTCMD then
it is set to 0 to make sure that ret is 0 when no error occurred.
