The interrupt affinity scheme used by this driver is incompatible with
multi-MSI as it implies moving the doorbell address to that of another 
MSI
group.  This isn't possible for multi-MSI, as all the MSIs must have 
the
same doorbell address. As such it is restricted to systems with a 
single
CPU.

Fixes: fc54bae28818 ("PCI: iproc: Allow allocation of multiple MSIs")
