 Log Message:
 add a quirk to disable MSI, and enable it for Intel SSD DC P4500
 
 this device seems to cause serious system responsiveness issues when configured
 to use MSI, while it works fine when configured for either INTx or MSI-X
 
 this is important so this works well under Xen Dom0, which doesn't
 support MSI-X yet
 
 fixes another issue reported as feedback for PR port-xen/55285 by Frank Kardel
