The following changes add new accessors to the XiveRouter required to

On POWER9, the KVM XIVE device uses priority 7 for the escalation
interrupts. On POWER10, the host can use a reduced set of priorities
and KVM will configure the escalation priority to a lower number. In
any case, the guest is allowed to use priorities in a single range :
[ 0 .. (maxprio - 1) ].
Introduce a 'hv-prio' property to represent the escalation priority
number and use it to compute the "ibm,plat-res-int-priorities"

Calls to the KVM XIVE device are guarded by kvm_irqchip_in_kernel(). This
ensures that QEMU won't try to use the device if KVM is disabled or if
an in-kernel irqchip isn't required.
When using ic-mode=dual with the pseries machine, we have two possible
interrupt controllers: XIVE and XICS. The kvm_irqchip_in_kernel() helper
will return true as soon as any of the KVM device is created. It might
lure QEMU to think that the other one is also around, while it is not.
This is exactly what happens with ic-mode=dual at machine init when
claiming IRQ numbers, which must be done on all possible IRQ backends,
eg. RTAS event sources or the PHB0 LSI table : only the KVM XICS device
is active but we end up calling kvmppc_xive_source_reset_one() anyway,
which fails. This doesn't cause any trouble because of another bug :
kvmppc_xive_source_reset_one() lacks an error_setg() and callers don't
see the failure.
Most of the other kvmppc_xive_* functions have similar xive->fd
checks to filter out the case when KVM XIVE isn't active. It
might look safer to have idempotent functions but it doesn't
really help to understand what's going on when debugging.
Since we already have all the kvm_irqchip_in_kernel() in place,
also have the callers to check xive->fd as well before calling
KVM XIVE specific code. This is straight-forward for the spapr
specific XIVE code. Some more care is needed for the platform
agnostic XIVE code since it cannot access xive->fd directly.
Introduce new in_kernel() methods in some base XIVE classes
for this purpose and implement them only in spapr.
In all cases, we still need to call kvm_irqchip_in_kernel() so that
compilers can optimize the kvmppc_xive_* calls away when CONFIG_KVM
isn't defined, thus avoiding the need for stubs.

On the P9 Processor, the thread interrupt context registers of a CPU
can be accessed "directly" when by load/store from the CPU or
"indirectly" by the IC through an indirect TIMA page. This requires to
configure first the PC_TCTXT_INDIRx registers.
Today, we rely on the get_tctx() handler to deduce from the CPU PIR
the chip from which the TIMA access is being done. By handling the
TIMA memory ops under the interrupt controller model of each machine,
we can uniformize the TIMA direct and indirect ops under PowerNV. We
can also check that the CPUs have been enabled in the XIVE controller.
This prepares ground for the future versions of XIVE.

SpaprInterruptControllerClass and PnvChipClass have an intc_create() method
that calls the appropriate routine, ie. icp_create() or xive_tctx_create(),
to establish the link between the VCPU and the presenter component of the
interrupt controller during realize.
There aren't any symmetrical call to be called when the VCPU gets unrealized
though. It is assumed that object_unparent() is the only thing to do.
This is questionable because the parenting logic around the CPU and
presenter objects is really an implementation detail of the interrupt
controller. It shouldn't be open-coded in the machine code.
Fix this by adding an intc_destroy() method that undoes what was done in
intc_create(). Also NULLify the presenter pointers to avoid having
stale pointers around. This will allow to reliably check if a vCPU has
a valid presenter.

It turns out that all the logic in the SpaprIrq::reset hooks (and some in
the SpaprIrq::post_load hooks) isn't really related to resetting the irq
backend (that's handled by the backends' own reset routines). Rather its
about getting the backend ready to be the active interrupt controller or
stopping being the active interrupt controller - reset (and post_load) is
just the only time that changes at present.
To make this flow clearer, move the logic into the explicit backend
activate and deactivate hooks.

This method depends only on the active irq controller. Now that we've
formalized the notion of active controller we can dispatch directly
through that, rather than dispatching via SpaprIrq with the dual
version having to do a second conditional dispatch.

These methods, like cpu_intc_create, really belong to the interrupt
controller, but need to be called on all possible intcs.
Like cpu_intc_create, therefore, make them methods on the intc and
always call it for all existing intcs.
