Indeed. Seems this particular combination has yet shown up (or we missed
it for docs). Add appropriate events/in_accel_value_available
entry to Documentation/ABI/sysfs-bus-iio

Whilst you are there, good to check that all the other ABI for this device
is listed in there. Given we mostly construct ABI from a bunch of parts, it
is easy to miss entries for particular combinations of channel type and thing.
