gpu: host1x: Port the HDMI vendor infoframe code the common helpers
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) Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Terje Bergström <tbergstrom@nvidia.com> Cc: linux-tegra@vger.kernel.org Signed-off-by: Damien Lespiau <damien.lespiau@intel.com> Reviewed-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Dave Airlie <airlied@gmail.com>
