[PATCH v3 9/9] media: vimc: Run multiple captures on same thread

[Kaaira Gupta]

If multiple captures try to enable stream, start their stream but do not
initialise the pipeline again. Also, don't start the thread separately.
Starting their streams will update the use count and their frames would
be processed by the already running thread.
