ffprobe xsd misses some attributes

[kokorin]

Summary of the bug: ffprobe XSD misses some attributes of side_data element.

<side_data_list>
	<side_data side_data_type="Display Matrix" displaymatrix="
00000000:            0       65536           0
00000001:       -65536           0           0
00000002:            0           0  1073741824
" rotation="-90"/>
</side_data_list>

Attributes displaymatrix and rotation are absent in ​ffprobe.xsd.

How to reproduce:
Get video recorded with Android or iPhone (may be other devices) and check it with ffprobe.

% ffprobe.exe -bitexact -print_format xml=x=1:q=1 -noprivate -show_data -show_streams .\VID_20180317_232636.mp4

Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.
