[PATCH 3/3] backlight: 88pm860x_bl: Use of_get_child_by_name() instead of refcount hack

[Geert Uytterhoeven]

of_find_node_by_name() calls of_node_put() on its "from" parameter.
To counter this, pm860x_backlight_dt_init() calls of_node_get() first.

Use of_get_child_by_name() instead to get rid of the refcount hack.
