ASoC: eureka-tlv320: Hold reference returned from of_find_xxx API

[ Upstream commit bfb735a3ceff0bab6473bac275da96f9b2a06dec ]

In eukrea_tlv320_probe(), we need to hold the reference returned
from of_find_compatible_node() which has increased the refcount
and then call of_node_put() with it when done.
