c63e56fe63 v4l2codecs: Fix tiled formats stride conversion
While adding arbitrary tile support, a round up operation was badly
converter. This caused the Y component of the stride to be 0. This
eventually lead to a crash in glupoad preceded by the following
assertion.

  gst_gl_buffer_allocation_params_new: assertion 'alloc_size > 0' failed

5980fb76e7 video: Add arbitrary tile dimensions support
In current tile representation, only tiles with power of two
width and height in bytes are supported. This limitation
prevents adding more complex tiles formats.

In this patch, we deprecate tile_ws and tile_hs from GstVideoFormatInfo and
replace if with an array of GstVideoTileInfo. Each plane tiles are then
described with their pixels width/height, line stride and total size.
The helper gst_video_format_info_get_tile_sizes() that depends on the
deprecated API is also being removed. This can simply be removed as it wasn't
in any stable release yet.

a6f8cc4b95 v4l2codecs: Add P010 pixel format
Copy V4L2_PIX_FMT_P010 define from linux header.
V4L2_PIX_FMT_P010 is the little endian definition of P010 so map
it GST_VIDEO_FORMAT_P010_10LE.
Add it v4l2 default video formats to allows v4l2 decoders to
enumerate and use it.

ab839f3642 v4l2codecs: Port to the new tile size helper
This will complete the scaling of width/height shift scaling
as only a partial implementation was made.

248f143fa3 v4l2codecs: Support YUV420M format
YUV420M format of V4L essentially is I420 with separate memory planes.
It's used by NVIDIA Tegra V4L decoder. Support this format by v4l2codecs.

bab9041c4b Port plugins to gst_video_format_info_extrapolate_stride()
This reduces code duplication and simplify addition of new
pixel formats into related plugins.
