mfd: twl6040: Fix child-node lookup
commit 85e9b13cbb130a3209f21bd7933933399c389ffe 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 node was prematurely freed, while the
child node was leaked.
Note that the CONFIG_OF compile guard can be removed as
of_get_child_by_name() provides a !CONFIG_OF implementation which always
fails.
