[PATCH] memory: of: Add of_node_put() when breaking out of for_each_child_of_node()

[Liang He <windhl@126.com>]

In of_get_ddr_timings() and of_lpddr3_get_ddr_timings(), we should
add the of_node_put() when breaking out of for_each_child_of_node()
as it will automatically increase and decrease the refcount.

Fixes: 976897dd96db ("memory: Extend of_memory with LPDDR3 support")
Fixes: e6b42eb6a66c ("memory: emif: add device tree support to emif driver")
