soc: atmel: fix device_node release in atmel_soc_device_init()
[ Upstream commit d3455ab798100f40af77123e7c2443ec979c546b ]
A device_node acquired via of_find_node_by_path() requires explicit
calls to of_node_put() when it is no longer needed to avoid leaking the
resource.
Instead of adding the missing calls to of_node_put() in all execution
paths, use the cleanup attribute for 'np' by means of the __free()
macro, which automatically calls of_node_put() when the variable goes
out of scope.
