ppc/xics: store the ICS object under the sPAPR machine

A list of ICS objects was introduced under the XICS object for the
PowerNV machine but, for the sPAPR machine, it brings extra complexity
as there is only a single ICS. To simplify the code, let's add the ICS
pointer under the sPAPR machine and try to reduce the use of this list
where possible.

Also, change the xics_spapr_*() routines to use an ICS object instead
of an XICSState and change their name to reflect that these are
specific to the sPAPR ICS object.

ppc/xics: remove set_nr_irqs() handler from XICSStateClass

Today, the ICS (Interrupt Controller Source) object is created and
realized by the init and realize routines of the XICS object, but some
of the parameters are only known at the machine level.

These parameters are passed from the sPAPR machine to the ICS object
in a rather convoluted way using property handlers and a class handler
of the XICS object. The number of irqs required to allocate the IRQ
state objects in the ICS realize routine is one of them.

Let's simplify the process by creating the ICS object along with the
XICS object at the machine level and link the ICS into the XICS list
of ICSs at this level also. In the sPAPR machine, there is only a
single ICS but that will change with the PowerNV machine.

Also, QOMify the creation of the objects and get rid of the
superfluous code.

xics: XICS should not be a SysBusDevice

Currently xics - the component of the IBM POWER interrupt controller
representing the overall interrupt fabric / architecture is
represented as a descendent of SysBusDevice. However, this is not
really correct - the xics presents nothing in MMIO space so it should
be an "unattached" device in the current QOM model.

Since this device will always be created by the machine type, not created
specifically from the command line, and because it has no migrated state
it should be safe to move it around the device composition tree.

Therefore this patch changes it to a descendent of TYPE_DEVICE, and
makes it an unattached device. So that its reset handler still gets
called correctly, we add a qdev_set_parent_bus() to attach it to
sysbus. It's not really clear that's correct (instead of using
register_reset()) but it appears to a common technique.

ppc patch queue 2016-10-28

This pull request supersedes and extends the one from 2016-10-26
(which had a build bug).

Highlights:
* SLOF (pseries guest firmware) update
* Enable a number of extra testcases on ppc / pseries
* Added the 'powernv' machine type
- Almost enough to be minimally usable
- But still missing necessary interrupt controller updates
* Cleanup and consolidation of NVRAM handling on several platforms
with related firmware
* Substantial cleanup to device tree construction
* Some more POWER9 instruction emulation
* Cleanup to handling of pseries option vectors and CAS reboot
handling (host/guest feature negotiation mechanism)
* Significant cleanups to handling of PCI devices in test cases
* New hotplug event infrastructure
* Memory hot unplug support for pseries
* Several bug fixes

The NVRAM cleanup affects some Sun sparc platforms as well as ppc
ones, but have been tested by the sparc maintainer (Mark Cave-Ayland).

The test additions also include substantial general changes to the
test framework that aren't strictly ppc related. They don't seem to
break tests on other platforms, they're for the benefit of enabling
tests on ppc and there isn't a specific maintainer for them, so
they're included in this tree.

This pull request supersedes ppc-for-2.8-20160922. There was a clang
build error in that, and I've also added one extra patch in the new pull.

Included in this set of ppc and spapr patches are:
* TCG implementations for more POWER9 instructions
* Some preliminary XICS fixes in preparataion for the pnv machine type
* A significant ADB (Macintosh kbd/mouse) cleanup
* Some conversions to use trace instead of debug macros
* Fixes to correctly handle global TLB flush synchronization in
TCG. This is already a bug, but it will have much more impact
when we get MTTCG
* Add more qtest testcases for Power
* Some MAINTAINERS updates
* Assorted bugfixes
* Add the basics of NUMA associativity to the spapr PCI host bridge

This touches some test files and monitor.c which are technically
outside the ppc code, but coming through this tree because the changes
are primarily of interest to ppc.

The "ICP" is a different object than the "XICS". For historical reasons,
we have a number of places where we name a variable "icp" while it contains

the code really confusing.

This is a mechanical replacement of all those instances to use the name
"xics" instead. There should be no functional change.
