[PATCH 09/13] net: mvneta: bm: add support for hardware buffer management

Buffer manager (BM) is a dedicated hardware unit that can be used by all ethernet ports of Armada XP and 38x SoC's. It allows to offload CPU on RX path by sparing DRAM access on refilling buffer pool, hardware-based filling of descriptor ring data and better memory utilization due to HW
