No. The #address-cells in the interrupt controller is necessary to
define the size of the unit address part of the unit interrupt specifier
of interrupt children. Re-read your spec :-)
Having it set to 0 provides the necessary definition so that the "right
hand" members of an interrupt map don't need a unit address in their
unit interrupt specifier.
