soc: xilinx: fix unhandled SGI warning message
[ Upstream commit 9c6724abf969251af53cdae525ad8100ec78d3c2 ]
Xen broadcasts SGI to each VM when multiple VMs run on Xen hypervisor. In
such case spurious SGI is expected if one event is registered by one VM and
not registered by another VM. We let users know that Unhandled SGI is not
error and expected if kernel is running on Xen hypervisor.
