OvmfPkg/MptScsiDxe: Probe PCI devices and look for MptScsi 

The MptScsiControllerSupported function is called on handles passed in
by the ConnectController() boot service and if the handle is the
lsi53c1030 controller the function would return success. A successful
return value will attach our driver to the device.
