v5: Re-arrange 5332 and 9574 compatibles to handle fallback usage in dts

v4: * v3 reused ipq9574 bindings for ipq5332. Instead add one for ipq5332
    * DTS uses ipq9574 compatible as fallback. Hence move ipq9574 to be able
      to use the 'reg' section for both ipq5332 and ipq9574. Else, dtbs_check
      and dt_binding_check flag errors.
