Krishna Gudipati 4507025d01 [SCSI] bfa: DMA memory allocation enhancement. 
- Modified the design such that each BFA sub-module will provide
  the amount of DMA and KVA memory needed by it and queues the
  same request to the global dma and kva info queues.
- During the memory allocation we iterate over this queue to allocate
  the dma and kva memory requested by sub-modules.
- The change is needed to avoid requesting the aggregate amount of memory
  needed by all the BFA sub-modules as one contiguous chunk.
