The header is headers/private/kernel/condition_variable.h, so it's a kernel
private API ATM. Drivers in the Haiku repository are free to use it (and
are encouraged to do so, if they need a condition variable API); they will
be adjusted accordingly, when (if) the API changes. Hoping that the atheros
driver will make it into the Haiku repository eventually, I'd say using
kernel private API is fine for it, too.
