When can_scale is FALSE, kmssink will push even upsteam to
videoconvert for resize, videoconvert will get buffer from kmssink
the buffer size need at least align to 4

If resize ratio is beyond the driver limitation, add limitation in

Kmssink need hold at least one original buffer to avoid vpu
overwrite the buffer still been displayed. Add buffer num to 2 to
workaround dcss drm video jitter issue.

When resize, show frame input buffer will be NULL, so need check
if buffer is NULL before dump hdr10 meta

drm setplane will block on vblank before return.
it’s a sync call. So no need do frame sync in kmssink.

when video size is same as display resolution, show frame will not do
retry because the setplane will never fail. But the scale result is not
correct. We can do this check by set a fake plane.

Implement videooverlay interface in kmssink, divided into two cases:
when driver supports scale, then we do refresh in show_frame(); if
not, send a reconfigure event to upstream and re-negotiate, using the
new size.

1. Support one texture for YUV format in dmabuf uploader
2. Propose ion dma-fd buffer pool to upstream to avoid memory copy
3. If upstream don't chose the proposed buffer pool, then create
   our own and do copy to avoid memory copy from CPU to GPU side
4. Add buffer alignmentw
