GXBB does not support 4K/UHD H264

[chewitt]

Playing 4K/UHD H264 media results in:

[ 238.595350] meson-vdec c8820000.video-decoder: Unsupported video width: 3840
[ 238.596788] meson-vdec c8820000.video-decoder: Aborting decoding session!

Maxime commented the vendor kernel required lenghty hacks to support 4K H264 so it has not been implemented in the current upstream (staging) driver.

NB: This is not about 10-bit H264 (the animé format) which is not supported in any Amlogic SoCs.
