a00d29867c fuzz, vmm: Avoid infinite loop in CMOS fuzzer 
With the addition of the spinning waiting for the exit event to be
received in the CMOS device a regression was introduced into the CMOS
fuzzer. Since there is nothing to receive the event in the fuzzer and
there is nothing to update the bit the that the device is looping on;
introducing an infinite loop.

Use an Option<> type so that when running the device in the fuzzer no
Arc<AtomicBool> is provided effectively disabling the spinning logic.

Fixes: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=61165

06dc708515 vmm: Only return from reset driven I/O once event received 
The reset system is asynchronous with an I/O event (PIO or MMIO) for
ACPI/i8042/CMOS triggering a write to the reset_evt event handler. The
VMM thread will pick up this event on the VMM main loop and then trigger
a shutdown in the CpuManager. However since there is some delay between
the CPU threads being marked to be killed (through the
CpuManager::cpus_kill_signalled bool) it is possible for the guest vCPU
that triggered the exit to be re-entered when the vCPU KVM_RUN is called
after the I/O exit is completed.

This is undesirable and in particular the Linux kernel will attempt to
jump to real mode after a CMOS based exit - this is unsupported in
nested KVM on AMD on Azure and will trigger an error in KVM_RUN.

Solve this problem by spinning in the device that has triggered the
reset until the vcpus_kill_signalled boolean has been updated
indicating that the VMM thread has received the event and called
CpuManager::shutdown(). In particular if this bool is set then the vCPU
threads will not re-enter the guest.

0149e65081 vm-device: support batch update interrupt source group GSI 
Split interrupt source group restore into two steps, first restore
the irqfd for each interrupt source entry, and second restore the
GSI routing of the entire interrupt source group.

This patch will reduce restore latency of interrupt source group,
and in a 200-concurrent restore test, the patch reduced the
average IOAPIC restore time from 15ms to 1ms.

4465bbaf38 devices: acpi: Add generic event controller 
Rather than overloading the GED device with the detection of what the
underlying event means move that to a new generic event controller.  The
advantage of this is that that the generic event controller can have a
_CRS that covers the memory for the OperationRegion (the ged driver
rejects _CRS entries that contain anything beyond the single interrupt)

957d3a7443 aarch64: Simplify GIC related structs definition 
Combined the `GicDevice` struct in `arch` crate and the `Gic` struct in
`devices` crate.

After moving the KVM specific code for GIC in `arch`, a very thin wapper
layer `GicDevice` was left in `arch` crate. It is easy to combine it
with the `Gic` in `devices` crate.

6dbc13627a devices: Emulate debug I/O based on pl011 
To emulate debug I/O port on arm64, we need trap from guest to VMM.
Generally, there are 3 ways to go:
1) execute a privilege intruction like "wfi";
2) access a system register;
3) access device MMIO region;
However, 1) and 2) often handled in kvm, thus 3) it's the choice.

There maybe lots of repeated work and enlarge the size of clh to develop
a new device, so it's better to reuse the current device. Luckily, I
find that pl011 is the eariest device initialized in kernel and, there
is reserved region in it which we can reuse for emulating debug I/O.
