ASoC: atmel: Add missing of_node_put() in at91sam9g20ek_audio_probe

BugLink: https://bugs.launchpad.net/bugs/1971497
[ Upstream commit f590797fa3c1bccdd19e55441592a23b46aef449 ]

This node pointer is returned by of_parse_phandle() with refcount
incremented in this function.
Calling of_node_put() to avoid the refcount leak.
