[PATCH] dt-bindings: dma: pl08x: Fix unevaluatedProperties warnings

[Rob Herring]

With 'unevaluatedProperties' support implemented, the example has
warnings on primecell properties and 'resets':

Documentation/devicetree/bindings/dma/arm-pl08x.example.dt.yaml: dma-controller@67000000: Unevaluated properties are not allowed ('arm,primecell-periphid', 'resets' were unexpected)

Add the missing reference to primecell.yaml and definition for 'resets'.
