Setting the H264_TRANSFORM_8X8 property only works on HFI versions

This patch changes venc_set_properties to only set the
H264_TRANSFORM_8X8 property if the hfi version is >=4xx.

I have an APQ8016-based board. Before this patch, the Venus driver
would simply fail with EINVAL when trying to request buffers
(VIDIOC_REQBUFS). With this patch, encoding works
(tested using gstreamer's v4l2h264enc).

Instead of doing these checks here you could do:

This may still deinit the session from [1] based on failure return value.

No, it will not fail because of:
