Rework embedded data documentation by removing the reference to the pixel
data stream. The specific documentation of the embedded data interface
will be elsewhere, in the near future either CCS or common raw camera
sensor model documentation.

 the most common data interface used by such sensors, embedded data can be
 available on other interfaces as well.
 
-Such sensors expose two internal sink pads (pads that have both the
-``MEDIA_PAD_FL_SINK <MEDIA-PAD-FL-SINK>`` and ``MEDIA_PAD_FL_INTERNAL
-<MEDIA-PAD-FL-INTERNAL>`` flags set) to model the source of the image and

+Embedded data support is indicated by the precence of an internal sink pad (pad

 In general, changing the embedded data format from the driver-configured values
 is not supported. The height of the metadata is device-specific and the width
