[PATCH] gstreamer: Add Y444 format support to the YUV list

[Antoine Bouyer]

'imx8-isi' pipeline provides support for 'YUV444' PixelFormat with YUV
streams, but it cannot be played with gstreamer adapter whereas
gstreamer's video format 'Y444' value suggests that it also supports
this format.

To add support of Planar 4:4:4 YUV format in gstreamer adapter, this patch
maps 'Y444' gstreamer video format with 'YUV444' libcamera PixelFormat.

Then below command example can be used to capture a stream with imx8-isi
pipeline:

  gst-launch-1.0 \
      libcamerasrc camera-name=<your_camera_name> ! \
      video/x-raw, format=Y444, width=1280, height=800 ! \
      queue ! \
      filesink location=/tmp/output
