Subject: [PATCH 2/6] media: mediatek: vcodec: Use meaningful decoder card name including chip name

The card name for the video decoder previously held a static platform
name, that was fixed to match MT8173. This obviously doesn't make sense
for newer chips. Since commit a8a7a278c56a ("media: mediatek: vcodec:
Change decoder v4l2 capability value"), this field was changed to hold
the driver's name, or "mtk-vcodec-dec". This doesn't make much sense
either, since this still doesn't reflect what chip this is.

Instead, fill in the card name with "MTxxxx video decoder" with the
proper chip number.

Fixes: a8a7a278c56a ("media: mediatek: vcodec: Change decoder v4l2 capability value")
