[PATCH] soc: fsl: rcpm: Fix refcount leak in copy_ippdexpcr1_setting

The of_find_compatible_node() function returns a node pointer with
refcount incremented, We should use of_node_put() on it when done
Add the missing of_node_put() to release the refcount.

Fixes: e95f287deed2 ("soc: fsl: handle RCPM errata A-008646 on SoC LS1021A")
