It's not uncommon for the particular device to support only a subset of
HDMI InfoFrames. It's not a big problem for the kernel, since we adopted
a model of ignoring the unsupported Infoframes, but it's a bigger
problem for the userspace: we end up having files in debugfs which do
mot match what is being sent on the wire.

Sort that out, making sure that all interfaces are consistent.
