media: mediatek: vcodec: decoder: Drop max_{width,height} from mtk_vcodec_ctx

This partially reverts commit b018be06f3c7 ("media: mediatek: vcodec:
Read max resolution from dec_capability").

After the previous patches:

- media: mediatek: vcodec: decoder: Fix 4K frame size enumeration
- media: mediatek: vcodec: decoder: Skip alignment for default resolution
- media: mediatek: vcodec: decoder: Fix resolution clamping in TRY_FMT

the max_{width,height} fields in |struct mtk_vcodec_ctx| no longer have
any real users. Remove them.
