q800: add default vendor and product information for scsi-cd devices

The MacOS CDROM driver uses a SCSI INQUIRY command to check that any SCSI CDROMs
detected match a whitelist of vendors and products before adding them to the
list of available devices.

Add known-good default vendor and product information using the existing
compat_prop mechanism so the user doesn't have to use long command lines to set
the qdev properties manually.
