From: Markus Armbruster <armbru@redhat.com>

We can't drop it, because the ISA device is entangled with the PCI
device, which we want to keep.  Disentangling it upstream would be
nice, but we're out of time.

Instead, make it unavailable with -device / device_add.  Suffices,
because the only other way to get it is via pc_vga_init() calling
isa_vga_init(), which it never does in RHEL, because it never gets a
null pci_bus argument.
