Subject: [PATCH 5/6] media: mediatek: vcodec: Use meaningful encoder card name including chip name

The card name for the video encoder previously held a static platform
name that was fixed to match MT8173. This obviously doesn't make sense
for newer chips. Since commit fd9f8050e355 ("media: mediatek: vcodec:
Change encoder 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 encoder" with the
proper chip number.

Fixes: fd9f8050e355 ("media: mediatek: vcodec: Change encoder v4l2 capability value")
