ARM: exynos: Fix a leaked reference by adding missing of_node_put
The call to of_get_next_child returns a node pointer with refcount
incremented thus it must be explicitly decremented after the last
usage.
Detected by coccinelle with warnings like:
arch/arm/mach-exynos/firmware.c:201:2-8: ERROR: missing of_node_put;
acquired a node pointer with refcount incremented on line 193,
but without a corresponding object release within this function.
