soc: samsung: exynos-pmu: fix use-after-free of interrupt generator node
The setup_cpuhp_and_cpuidle() parses the device tree node for the
interrupt generation block via of_parse_phandle() and decrements its
reference count using of_node_put() immediately after fetching the resource
address. However, later the intr_gen_node pointer is passed into
of_syscon_register_regmap().
Fix this by declaring intr_gen_node with __free() and removing
of_node_put().
