[PATCH] ARM: ux500: Fix refcount leak in ux500_pm_domains_init

[Miaoqian Lin]

of_irq_find_parent() returns a node pointer with refcount incremented,
We should use of_node_put() on it when not needed anymore.
Add missing of_node_put() in the error path to avoid refcount leak.

Fixes: cd931dcfda5e ("ARM: ux500: Initial support for PM domains")
