I just wrote the bits to define and pack HDMI vendor specific infoframe. Port the host1x driver to use those so I can refactor the infoframe code a bit more.
This changes the length of the infoframe payload from 6 to 5, which is enough for the "frame packing" stereo format.
v2: Pimp up the commit message with the note about the length (Ville Syrjälä)
