iommu: fsl_pamu: use for_each_of_cpu_node iterator

robherring · robherring · commit a9a455e854cd · 2018-09-28T14:25:58.000-05:00
Use the for_each_of_cpu_node iterator to iterate over cpu nodes. This
has the side effect of defaulting to iterating using "cpu" node names in
preference to the deprecated (for FDT) device_type == "cpu".
