[media] media-doc: Fix MFC display delay control doc 

The V4L2_CID_MPEG_MFC51_VIDEO_DECODER_H264_DISPLAY_DELAY_ENABLE control
is a boolean but was documented as a integer. The documentation was
also slightly miss-leading.

</row><row><entry spanname="descr">If the display delay is enabled then the decoder has to return a
CAPTURE buffer after processing a certain number of OUTPUT buffers. If this number is low, then it may result in
buffers not being dequeued in display order. In addition hardware may still use those buffers as reference, thus
application should not write to those buffers. This feature can be used for example for generating thumbnails of videos.
Applicable to the H264 decoder.
