[PATCH] net: mvneta: explicitly disable BM on 64bit platform

From: Jisheng Zhang
Date: Wed Mar 30 2016 - 09:29:30 EST

The mvneta BM can't work on 64bit platform, as the BM hardware expects
buf virtual address to be placed in the first four bytes of mapped
buffer, but obviously the virtual address on 64bit platform can't be
stored in 4 bytes. So we have to explicitly disable BM on 64bit
