drivers/video/backlight/88pm860x_bl.c: add missing of_node_put()

Browse Source 
of_find_node_by_name() returns a node pointer with refcount incremented,
use of_node_put() on it when done.

of_find_node_by_name() will call of_node_put() against the node pass to
from parameter, thus we also need to call of_node_get(from) before calling
of_find_node_by_name().
