Drives defined with if!=none, character devices defined with -serial
and -parallel, network devices defined with -net nic are all for board
initialization to wire up. Board code calls drive_get() or similar to
find them, and creates devices with their qdev properties set
accordingly.
Except a few devices go on fishing expeditions on their own instead of
exposing a drive property for board code to set.
We can't fix this in time for the release, so do the next best thing:
contain the mistakes as far as possible so they don't become ABI:
* Mark them all with suitable FIXME comments [PATCH 1-3].
* sdhci-pci is new, set cannot_instantiate_with_device_add_yet to make
it unavailable with -device [PATCH 4].
* A few more aren't currently available with -device, set
cannot_instantiate_with_device_add_yet to ensure they stay
unavailable [PATCH 5].
* Left alone: m25p80-generic and its derivatives[*], ssi-sd, pc87312.
I suspect these can't be used sanely with -device / device_add, and
cannot_instantiate_with_device_add_yet for them would be just fine,
but I feel we're too close to the release to argue this now.
