/**
* Allocate memory and initialize the FPA pools using memory
* from cvmx-bootmem. Sizes of each element in the pools is
* controlled by the cvmx-config.h header file. Specifying
* zero for any parameter will cause that FPA pool to not be
* setup. This is useful if you aren't using some of the
* hardware and want to save memory.
*
* @packet_buffers:
* Number of packet buffers to allocate
* @work_queue_entries:
* Number of work queue entries
* @pko_buffers:
* PKO Command buffers. You should at minimum have two per
* each PKO queue.
* @tim_buffers:
* TIM ring buffer command queues. At least two per timer bucket
* is recommened.
* @dfa_buffers:
* DFA command buffer. A relatively small (32 for example)
* number should work.
* Returns Zero on success, non-zero if out of memory
