[PATCH 3/4] media: verisilicon: Don't offer VP8 above 1080p on the Rockchip VDPU2

[Arun Iyengar via B4 Relay <devnull+aiyengar1990.gmail.com@kernel.org>]

From: Arun Iyengar <aiyengar1990@gmail.com>

The VDPU2 decoder format tables (RK3328, RK3568, RK3588 VPU121) and the
RK3399 one let the VP8 OUTPUT format go up to 3840x2160, but their only
CAPTURE format, NV12, stops at 1920x1088, and the CAPTURE size is
clamped to it. A 4K VP8 stream is therefore accepted on OUTPUT and then
decoded into a 1920x1088 buffer: on RK3588 GStreamer v4l2slvp8dec runs
into "gst_video_frame_map_id: assertion 'info->width <= meta->width'
failed" for every frame of a 3840x2160 stream and none of the frames
match FFmpeg.

Nothing above 1080p can be decoded with these tables, so don't
advertise it: limit VP8 to the 1920x1088 of the other codecs and of the
CAPTURE format. Userspace that checks VIDIOC_ENUM_FRAMESIZES, and the
S_FMT clamping, then know that a 4K VP8 stream needs another decoder.
