There are multiple models of the panic device, the address type is only
one and is valid only for "isa" model.
To not break the virt-install/virt-xml the command line parser needs to
be updated. Before this patch there was only one parameter that
configured the "iobase". Now the first parameter configures a model
but to keep it backward compatible it follows these rules:
1. there is only one parameter and it matches known model:
--panic isa
<panic model='isa'>
<address iobase='0x505' type='isa'/>
</panic>
2. there is only one parameter and it doesn't match any model:
--panic 0x505
<panic model='isa'>
<address iobase='0x505' type='isa'/>
</panic>
3. there are two parameters:
--panic isa,iobase=0x505
<panic model='isa'>
<address iobase='0x505' type='isa'/>
</panic>
