This was in the example, but otherwise wasn't documented before. And the 
Linux driver doesn't need it. So let's drop 'interrupt-names' because it 
is pointless here. 'spdif' is redundant because this the the spdif 
block. 'interrupt' is redundant because it's only interrupts in this 
list.

Don't forget the example.

With that,
