[dpdk-dev] [PATCH] doc: add deprecation notice on timer lib cleanup

Due to an upcoming fix to allow the timer library to safely free its
allocations during the finalize() call[1], an ABI change will be
required. A new lock will be added to the rte_mem_config structure,
which will be used by the timer library to synchronize init/finalize
calls among multiple processes.
