[PATCH v14 2/8] media: v4l2: Allow M2M job queuing w/o streaming CAP queue

[Sebastian Fricke <sebastian.fricke@collabora.com>]

Allow decoder drivers to enable set the ignore_streaming flag on their
CAPTURE queue, to allow queuing jobs to the M2M ready queue and perform
firmware sequence analysis with just a streaming OUTPUT queue and
available bitstream data.
