Hmm, the heartbeat and timer triggers do not need trigger sources. If
we want to deprecate linux,default-trigger device tree property for
these triggers also, this method should look to `function` DT property
for heartbeat and timer triggers.

In that case the name should be changed to something like
of_is_valid_default_for, or something like that.
