[libvirt PATCH 06/10] qemu: enable support for ESP SCSI controller family

The NCR53C90 is the built-in SCSI controller on all sparc machine types,
but not sparc64. Note that it has the fixed alias "scsi", which differs
from our normal naming convention of "scsi0".
The DC390 and AM53C974 are PCI SCSI controllers that can be added to any
PCI machine.
