The "#address-cells" property should be completely absent,
even; for interrupt matching, that means "treat as 0, no
unit address used in interrupt mapping, just the interrupt
number", and for the "normal" purpose (defining the format
of devices on the bus rooted at / represented by this node)
it means "there is no such bus" -- this is different from
#address-cells = 0.

I'd rather have it present and explicitely set to 0,

It is not the "right thing" to do, but should be harmless
in most situations.

which happens to be
what both Apple and IBM OF implementations also do. Have you verified 
if
the linux parser behaves properly if it's absent ?

No, I haven't.  I prefer following the standard instead of simply
making the code work with one or two implementations; I hope
you did the same :-)

If it doesn't work, it's simply a bug in Linux.
