[PATCH 1/2] ASoC: da7218: fix fix child-node lookup

[Johan Hovold]

Fix child-node lookup during probe, which ended up searching the whole
device tree depth-first starting at the parent rather than just matching
on its children.

To make things worse, the parent codec node was also prematurely freed.
