Bumps iced-x86 from 1.10.3 to 1.11.0.
Manual update of the code was needed since memory_displacement() was
deprecated and replaced with either memory_displacement32() or
memory_displacement64().

On AArch64, interrupt controller (GIC) is emulated by KVM. VMM need to
set IRQ routing for devices, including legacy ones.
Before this commit, IRQ routing was only set for MSI. Legacy routing
entries of type KVM_IRQ_ROUTING_IRQCHIP were missing. That is way legacy
devices (like serial device ttyS0) does not work.
The setting of X86 IRQ routing entries are not impacted.

Add API to the hypervisor interface and implement for KVM to allow the

These need to be updated together as the kvm-ioctls depends upon a
strictly newer version of kvm-bindings which requires a rebase in the CH
fork.

So far we've only had the need to emulate one instruction. There is no
need to use a HashMap when a simple tuple for the initial mapping will
do.
We can bring back the HashMap once more sophisticated use cases surface.

In particular update for the vmm-sys-util upgrade and all the other
dependent packages. This requires an updated forked version of
kvm-bindings (due to updated vfio-ioctls) but allowed the removal of our
forked version of kvm-ioctls.
The changes to the API from kvm-ioctls and vmm-sys-util required some
other minor changes to the code.

We don't have an easy way to figure out if a GPA points to normal memory
or device memory, but the guest's normal memory regions shouldn't
overlap with device regions. We can simply try to do a normal memory
read / write, and proceed to do device memory read / write if that
fails.

OVMF would use string IO on those ports. String IO has not been
implemented, so that leads to panics.
Skip them explicitly in MSHV. Leave a long-ish comment in code to
explain the situation. We should properly implement string IO once it
becomes feasible / necessary.
