[PATCH 2/2] omap3isp: Don't set streaming state on random subdevs

[Sakari Ailus <sakari.ailus@linux.intel.com>]

The streaming state should be set to the first upstream sub-device only,
not everywhere, for a sub-device driver itself knows how to best control
the streaming state of its own upstream sub-devices.
