[PATCH 3/3] ASoC: eukrea-tlv320: fix a leaked reference by adding missing of_node_put

[Wen Yang]

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/eukrea-tlv320.c:121:3-9: ERROR: missing of_node_put; acquired a 
node pointer with refcount incremented on line 102, but without a correspo    
nding object release within this function.

nding object release within this function.
