Subject: [PATCH 13/21] powerpc: 8xx: get cpu node with of_get_cpu_node

From: Rob Herring <[email-masked]>
Date: Wed, 5 Sep 2018 14:37:30 -0500

"device_type" use is deprecated for FDT though it has continued to be used
for nodes like cpu nodes. Use of_get_cpu_node() instead which works using
node names by default. This will allow the eventually removal of cpu
device_type properties.

Also, fix a leaked reference and add a missing of_node_put.

Please ack and I will take via the DT tree. This is dependent on the
first 2 patches.
