Dropping the const qualifiers prevents "passing argument 1 of ‘of_node_put’ discards ‘const’ qualifier from pointer target type" type warnings when compiling the code dropping reference to cpu_of_node, codec_of_node or platform_of_node with with an of_node_put() function call.
This lets us to avoid casting to struct device_node * or caching variables internally in drivers just to be able to properly drop a reference to the OF node on clean up paths.
