[PATCH 2/3] media: imx-csi: explicitly start media pipeline on pad 0

[Michael Tretter <m.tretter@pengutronix.de>]

entity->pads is an array that contains all the pads of an entity.

Calling __media_pipeline_start() or __media_pipeline_stop() on the pads,
implicitly starts the pipeline with the first pad in this array as
origin.

Explicitly use the first pad to start the pipeline to make this more
obvious to the reader.
