This should be rather just "pmic", because the examples have
address-cells=1 and size-cells=1, which is not correct in this context.

But there's a 'reg' property so you can't drop the unit-address. The bus 
node (spmi) needs to be added.

reg also can be dropped. I am not sure whether parent PMIC bus is
important here.
