VP9 support for Amlogic s905x

Hello,

New Amlogic s905x has hardware decoder for vp9. But Kodi doesn’t support it.

Amlogic sources for s905x can be found here – http://openlinux.amlogic.com:8000/downlo…35f.tar.gz – reference board name for s905x – p212
I built linux from this sources with kodi 16.1 (with amcodec enabled), and vp9 in Kodi doesn’t play throughout amcodec (in kplayer it does).

I checked if Kodi 17 supports it but didn’t found any related changes on github.
