Since "thermal/of: Support cooling device ID in cooling-spec", I could
be 2 or 3. I don't know if I should use enum [2, 3] or just go
directly to the new const: 3.
My test device has only the 0 channel in use and 2 is fine for now.

Sashiko also asked to require #pwm-cells, but it would mean to
implement a parser for that too. I don't know if it is worth it but I
can do it if needed.
