I am not happy that the original binding has the interrupts as
'mandatory'. Maybe the binding author did not have more use cases in mind.
Anyway I think that it can go to u-boot without this interrupts property
as it's surely unused and there is no interrupt controller at the moment
in the DT.
If nobody has another opinion that is...
