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

In an ideal world, machines can be built by wiring devices together
with configuration, not code. Unfortunately, that's not the world we
live in right now. We still have quite a few devices that need to be
wired up by code. If you try to device_add such a device, it'll fail
in sometimes mysterious ways. If you're lucky, you get an
unmysterious immediate crash.
To protect users from such badness, DeviceClass member no_user used to
make device models unavailable with -device / device_add, but that
regressed in commit 18b6dad. The device model is still omitted from
help, but is available anyway.
Attempts to fix the regression have been rejected with the argument
that the purpose of no_user isn't clear, and it's prone to misuse.
This commit clarifies no_user's purpose. Anthony suggested to rename
it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which
I shorten somewhat to keep checkpatch happy. While there, make it
bool.
Every use of cannot_instantiate_with_device_add_yet gets a FIXME
comment asking for rationale. The next few commits will clean them
all up, either by providing a rationale, or by getting rid of the use.
With that done, the regression fix is hopefully acceptable.

Add a linked list of keyboard handlers. Added handlers will go
to the head of the list. Removed handlers will be zapped from
the list. The head of the list will be used for events.
This fixes the keyboard-dead-after-usb-kbd-unplug issue, key events
will be re-routed to the ps/2 kbd instead of being discarded.
