[ Upstream commit a8fef9ba58c9966ddb1fec916d8d8137c9d8bc89 ]
Booting 4.20 on SolidRun Clearfog issues this warning with DMA API
debug enabled:
WARNING: CPU: 0 PID: 555 at kernel/dma/debug.c:1230 check_sync+0x514/0x5bc

...
This appears to be caused by mvneta_rx_hwbm() calling
dma_sync_single_range_for_cpu() with the wrong struct device pointer,
as the buffer manager device pointer is used to map and unmap the
buffer. Fix this.
