New ARM boards are generally expected to boot their secondary CPUs
via the PSCI interface, rather than ad-hoc "loop around in holding
pen code" as hw/arm/boot.c implements. In particular this is
necessary for mach-virt kernels. For KVM we achieve this by creating
the VCPUs with a feature flag marking them as starting in PSCI
powered-down state; the guest kernel will then make a PSCI call
(implemented in the host kernel) to start the secondaries at
an address of its choosing once it has got the primary CPU up.

Implement this setting of the feature flag, controlled by a
qdev property for ARMCPU, which board code can set if it is a
PSCI system.

Device trees created with create_device_tree() may not have any
entries in their reservemap, because the FDT API requires that the
reservemap is completed before any FDT nodes are added, and
create_device_tree() itself creates a node.  However we were not
calling fdt_finish_reservemap(), which meant that there was no
terminator in the reservemap list and whatever happened to be at the
start of the FDT data section would end up being interpreted as
reservemap entries.  Avoid this by calling fdt_finish_reservemap()
to add the terminator.

There are a number of places where it would be convenient for ARM
code to have working definitions of KVM constants even in code
which is compiled with CONFIG_KVM not set. In this situation we
can't simply include the kernel KVM headers (which might conflict
with host header definitions or not even compile on the compiler
we're using) so we have to redefine equivalent constants.
Provide a mechanism for doing this and checking that the values
match, and use it for the constants we're currently exposing
via an ad-hoc mechanism.

 - Enable QEMU support for KVM-VFIO device
 - Additional Nvidia x-vga quirk to ACK MSI interrupts
 - Debug options to disable MSI/X KVM acceleration
 - Fix to cleanup MSI-X vectors on shutdown and avoid IRQ route leaks

The KVM-VFIO device support enables KVM to manage how it handles
coherency instructions in the presence of non-coherent I/O.  Dave
Airlie had noted that the Nvidia MSI ACK support here may just be
scratching the surface, but it's better than what we have now and
it's only enabled via the x-vga option, so I'm willing to add since
it does enable some users.

We were relying on msix_unset_vector_notifiers() to release all the
vectors when we disable MSI-X, but this only happens when MSI-X is
still enabled on the device.  Perform further cleanup by releasing
any remaining vectors listed as in-use after this call.  This caused
a leak of IRQ routes on hotplug depending on how the guest OS prepared
the device for removal.

It's sometimes useful to be able to verify interrupts are passing
through correctly.
