backlight: as3711_bl: Fix Device Tree node lookup

commit 4a9c8bb2aca5b5a2a15744333729745dd9903562 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 mfd node was also prematurely freed.
