For format V4L2_PIX_FMT_VC1_ANNEX_G,
the separate codec data is required only once.
The repeated codec data may introduce some decoding error.
so drop the repeated codec data.
It's amphion vpu's limitation
Fixes: e670f5d672ef ("media: amphion: only insert the first sequence startcode for vc1l format")
