This is not correct. The fix for the above warning is to add
'#power-domain-cells' to the properties list here. You can't just
reference the schema because you have to define the value of
'#power-domain-cells' for this provider.
Generally, we only add a $ref to providers if they have child nodes
(e.g. are a bus).
