b0ae5c69e1 ppc/pnv: Remove PnvOCC::psi link
Use an anonymous output GPIO line to connect the OCC device with the
PSIHB device and raise the appropriate PSI IRQ line depending on the
processor model.

8bf682a349 ppc/pnv: Add a OCC model for POWER10
Our OCC model is very mininal and POWER10 can simply reuse the OCC
model we introduced for POWER9.

23a782eb66 ppc/pnv: change the PowerNV machine devices to be non user creatable
The PowerNV machine emulates an OpenPOWER system and the PowerNV chip
devices are models of the internal logic of the POWER processor. They
can not be instantiated by the user on the QEMU command line.

The PHB3/PHB4 devices could be an exception in the future after some
rework on how the device tree is built. For the moment, exclude them
also.

3a1b70b66b ppc/pnv: Fix OCC common area region mapping
The OCC common area is mapped at a unique address on the system and
each OCC is assigned a segment to expose its sensor data :

  | Start (Offset from | End           | Size     |Description            |
  | BAR2 base address) |               |          |                       |

  -------------------------------------------------------------------------

Maximum size is 1.5MB.

We could define a "OCC common area" memory region at the machine level
and sub regions for each OCC. But it adds some extra complexity to the
models. Fix the current layout with a simpler model.

ee3d27138d ppc/pnv: Link "psi" property to PnvOCC::psi pointer
The OCC object has both a pointer and a "psi" property pointing to the
PSI object. Confusing bugs could arise if these ever go out of sync.

Change the property definition so that it explicitely sets the pointer.

d5938f29fe Clean up inclusion of sysemu/sysemu.h
In my "build everything" tree, changing sysemu/sysemu.h triggers a
recompile of some 5400 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

Almost a third of its inclusions are actually superfluous.  Delete
them.  Downgrade two more to qapi/qapi-types-run-state.h, and move one
from char/serial.h to char/serial.c.

hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and
stubs/semihost.c define variables declared in sysemu/sysemu.h without
including it.  The compiler is cool with that, but include it anyway.

This doesn't reduce actual use much, as it's still included into
widely included headers.  The next commit will tackle that.

650d103d3e Include hw/hw.h exactly where needed
In my "build everything" tree, changing hw/hw.h triggers a recompile
of some 2600 out of 6600 objects (not counting tests and objects that
don't depend on qemu/osdep.h).

The previous commits have left only the declaration of hw_error() in
hw/hw.h.  This permits dropping most of its inclusions.  Touching it
now recompiles less than 200 objects.

0722d05ad8 ppc/pnv: Add OCC model stub with interrupt support
The OCC is an on-chip microcontroller based on a ppc405 core used
for various power management tasks. It comes with a pile of additional
hardware sitting on the PIB (aka XSCOM bus). At this point we don't
emulate it (nor plan to do so). However there is one facility which
is provided by the surrounding hardware that we do need, which is the
interrupt generation facility. OPAL uses it to send itself interrupts
under some circumstances and there are other uses around the corner.

So this implement just enough to support this.
