ASoC: cros_ec_codec: Fix refcount leak in cros_ec_codec_platform_probe
[ Upstream commit 0a034d93ee929a9ea89f3fa5f1d8492435b9ee6e ]
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
