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.
Fixes: c0cf5bdde46c ("rdma/siw: addition to kernel build environment")
