ASoC: twl4030: fix child-node lookup

commit 15f8c5f2415bfac73f33a14bcd83422bcbfb5298 upstream.

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,
while the child node was leaked.

Fixes: 2d6d649a2e0f ("ASoC: twl4030: Support for DT booted kernel")
