ARM: sunxi: 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 the following warnings: ./arch/arm/mach-sunxi/platsmp.c:55:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 46, but without a corresponding object release within this function. ./arch/arm/mach-sunxi/platsmp.c:138:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 129, but without a corresponding object release within this function.
