RMDA/siw: Require a 64 bit arch
The new siw driver fails to build on i386 with drivers/infiniband/sw/siw/siw_qp.c:1025:3: error: invalid output size for constraint '+q' smp_store_mb(*cq->notify, SIW_NOTIFY_NOT); As it is using 64 bit values with the smp_store_mb. Since the entire scheme here seems questionable, and we are in the merge window, fix the compile failures by disabling 32 bit support on this driver. A proper fix will be reviewed post merge window.
