[PATCH v3 08/14] media: Documentation: Additional streams generally don't harm capture

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

Having extra streams on the source end of the link that cannot be captured
by the sink sub-device generally are not an issue, at least not on CSI-2
bus. Still document that there may be hardware-specific limitations. For
example on parallel bus this might not work on all cases.
