If you are saying this is the only location we'll ever find 
'ieee802.3-pse', then defining it here is okay. Otherwise, it 
needs to be it's own file so there's exactly 1 type definition. As 
you've said it might have cells by defining #pse-cells, 'phandle' is 
the wrong type. 'phandle-array' is what you want, but then actual users 
need to define how many entries (i.e. maxItems). Just like all the 
other provider/consumer bindings are structured.
