ASoC: mt6797-mt6351: Fix refcount leak in mt6797_mt6351_dev_probe
[ Upstream commit 7472eb8d7dd12b6b9b1a4f4527719cc9c7f5965f ]
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.
Fixes: f0ab0bf250da ("ASoC: add mt6797-mt6351 driver and config option")
