These per-rail supply properties (vin1-supply through dldoin2-supply)
are not declared in the spacemit,p1.yaml binding, which only has
vin-supply.  With unevaluatedProperties: false on the PMIC node, these
will cause dtbs_check failures.  The binding needs to be updated to
match, or these should remain as the single vin-supply.
