avcodec/v4l2: set sizeimage param for non-raw buffers [fixes #6716]
Some V4L2 drivers fail to allocate buffers when sizeimage is not set
to a max value. This is indeed the case for s5p-mfc [1]
Most drivers should be able to calculate this value from the frame
dimensions and format - or at least have their own default.
However since this work around should not impact those drivers doing
the "right thing" this commit just provides such a default.
The calculations were extracted from the v4l2 driver used to develop
the ffmpeg v4l2_m2m support [2]. See venc.c and vdec.c
