Allow specifying the threshold for which the channels configured as
digital input change state.

Running dt_binding_check on this with a too small or large value in
the example does give me an error, but the multipleOf does not seem to
be enforced; the value 1234567 is not flagged. I don't know if that's
expected (maybe I have too old versions of something).
