With gstreamer 1.19.3 all attempts to capture video in YUV formats on
our Allwinner H3-based custom board with an ov5640 sensor result in
pipeline crashes with the following messages:
Device '/dev/video0' does not support 2:0:0:0 colorimetry
Additional debug info:
Device wants 2:0:0:0 colorimetry
Fix this by setting the correct colorspace in sun6i_video_try_fmt().

Actually there is a second issue with sun6i_video_try_fmt(): reported
bytesperline is wrong for planar YUV formats, but I believe it will be
fixed by [1].
