This interface can be used for example by firmware to print
debug messages. Here is domain xml example:
<serial type='pty'>
<target type='isa-serial' port='0'>
<model name='isa-debugcon'/>
</target>
<address type='isa' iobase='0x402'/>
</serial>
Add checks to make sure this new serial type won't be reported
as back-compat console.
