[PATCH 04/23] pmdomain: imx: fix OF node refcount

[Bartosz Golaszewski]

for_each_child_of_node_scoped() decrements the reference count of the
nod after each iteration. Assigning it without incrementing the refcount
to a dynamically allocated platform device will result in a double put
in platform_device_release(). Add the missing call to of_node_get().
