isa: Clean up use of cannot_instantiate_with_device_add_yet
Drop it when there's no obvious reason why device_add could not work. Else keep and document why. * isa-fdc: drop * i8042: drop, even though its I/O base is hardcoded (because you could conceivably still add one to a board that has none), and even though PC board code wires up the A20 line (because that wiring is optional) * port92: keep because it needs additional wiring by port92_init() * mc146818rtc: keep because it needs to be wired up by rtc_init() * m48t59_isa: keep because needs to be wired up by m48t59_init_isa() * isa-pit, kvm-pit: keep (in their abstract base pic-common) because the PIT needs additional wiring by board code, depending on HPET presence * pcspk: keep because of pointer property pit, and because realize sets global pcspk_state * vmmouse: keep because of pointer property ps2_mouse * vmport: keep because realize sets global port_state * isa-i8259, kvm-i8259: keep (in their abstract base pic-common), because the PICs' IRQ input lines are set up by board code, and the wiring of the slave to the master is hard-coded in device model code Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
