Subject: [PATCH 10/50] LOCAL: media: meson: vdec: disable MPEG1/MPEG2 hardware
decoding
The MPEG1/2 decoder is broken and nobody has volunteered to poke
code and fix it. As media is mostly SD (and never over 1080p)
resolution most boards can software decode it. So lets disable
hardware decoding for now.
