[libvirt] [PATCH 1/4] conf: add 'isa-bridge' PCI controller model

Sun Feb 10 15:08:52 UTC 2019
Introduce 'isa-bridge' PCI controller model that looks this way
in domain XML:
...
<controller type='pci' index='1' model='isa-bridge'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x01'
function='0x0'/>
</controller>
...
Currently, this is needed by the bhyve driver to allow choosing a
specific PCI address for that. In bhyve, this controller is used to
attach serial ports and a boot ROM.
