media: amphion: drop repeated codec data for vc1g format

Browse Source 
[ Upstream commit e1d2ccc2cdd6333584aa3d5386dc667d0837c48f ]

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
