I copied the EDID off of some random 1080p HDMI monitor,
probably using something like:
xxd -g1 /sys/class/drm/card0-HDMI-A-1/edid | cut -c 9-56

Ah right, I still have no proper fix for that. v4l-ctl bails out if it
can't VIDIOC_QUERYCAP, which is an ioctl not supported on subdevices.
I have just patched it out locally:

capabilities = vcap.capabilities;
if (capabilities & V4L2_CAP_DEVICE_CAPS)
capabilities = vcap.device_caps;

Note that setting the EDID is not necessary if you can force the mode on
your HDMI source.
