ASoC: fsl_utils: fix a leaked reference by adding missing of_node_put

[ Upstream commit c705247136a523488eac806bd357c3e5d79a7acd ]

The call to of_parse_phandle returns a node pointer with refcount
incremented thus it must be explicitly decremented after the last
usage.

Detected by coccinelle with the following warnings:
./sound/soc/fsl/fsl_utils.c:74:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 38, but without a corresponding     object release within this function.
