When the DeviceInfo code was removed, the comment describing
qdev_subclass_init() was left in the code by mistake. Remove it.

From: Anthony Liguori <aliguori@us.ibm.com>
Header file dependency is a frickin' nightmare right now. cpu.h tends to get
included in our 'include everything' header files but qdev also needs to include
those headers mainly for qdev-properties since it knows about CharDriverState
and friends.
We can solve this for now by splitting out qdev.h along the same lines that we
previously split the C file. Then cpu.h just needs to include qdev-core.h
[ehabkost: re-add DEFINE_PROP_PCI_HOST_DEVADDR, that was removed on the
original patch (by mistake, I guess)]

Generally I am still in favor of doing such a per-topic file split, in
whatever way exactly we proceed with CPU-as-a-device.
If this is supposed to go through my CPU queue then I would prefer to
move the [ehabkost: ...] lines chronologically between the Sobs fwiw.
What I would insist on is mentioning both new file names in the commit
message (qdev-core.h and qdev-properties.h iiuc) since the +++ stats are
ambiguous.
I spotted the following textual discrepancy:

[snip]
"Individual" became "Indicidual" and the comment seems misplaced, which
makes myself ask whether this split was not done safely via copy&paste?

Andreas

This change should help on two things:
- Allowing DeviceState to be used by *-user;
- Writing qdev unit tests without pulling too many dependencies.
Note that there are two parts that depend on code compiled only on
qemu-system-*, but are still inside qdev.c:
- vmstate handling
- reset function registration.
Those two parts will be handled later, by moving that code to
qdev-system.c but keeping weak symbols for *-user.

isolate it so it can be moved to qdev-system.c.

it's necessary for making CPU child of DEVICE without
causing circular header deps.

Igor's qemu_system_powerdown cleanup has hit master now, so
sysemu.h doesn't need to include hw/irq.h now.
(You may find that this means some files which were implicitly
getting hw/irq.h now need to include it directly, of course.)

This way, the files can be moved to the qom/ directory as-is.

The code depends on some functions from qemu-option.o, so add
qemu-option.o to universal-obj-y to make sure it's included.

Ping for Peter,
This is a prerequisite for you ARM CPU reset as a GPIO idea. I'm on
board with it, if we can get this through which will make it
relatively painless to refactor my series.

Peter
