This commit enables some mmio-related integration test cases on
AArch64, including:
* some vhost_user test cases
* virtio-blk test cases
* pmem test cases
Also this commit contains a bug fix in creating virtio-blk device.
Previously, when creating the FDT, the virtio-blk device was
labeled in the reverse order of address allocation.

Make set_gsi_routing take a list of IrqRoutingEntry. The construction of
hypervisor specific structure is left to set_gsi_routing.
Now set_gsi_routes, which is part of the interrupt module, is only
responsible for constructing a list of routing entries.
This further splits hypervisor specific code from hypervisor agnostic
code.

The only driver writable field in the virtio-block specification is the
writeback one. Check that the offset being written to is for that field
and update it.

The retry order to create virtual GIC is GICv3-ITS, GICv3 and GICv2.
But there was not log message to show what was finally created.
The log messages also mute the warning for unused "log" crate.

With recent changes (#1030#1084), the '/vm.remove-device' API is no
longer restricted to remove VFIO PCI devices. It now supports (almost)
all hotpluggable devices, e.g. disk/net/pmem/fs/vsock.

SGX expects the EPC region to be reported as "reserved" from the e820
table. This patch adds a new entry to the table if SGX is enabled.
Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com>
The support for SGX is exposed to the guest through CPUID 0x12. KVM
passes static subleaves 0 and 1 from the host to the guest, without
needing any modification from the VMM itself.
But SGX also relies on dynamic subleaves 2 through N, used for
describing each EPC section. This is not handled by KVM, which means
the VMM is in charge of setting each subleaf starting from index 2
up to index N, depending on the number of EPC sections.
These subleaves 2 through N are not listed as part of the supported
CPUID entries from KVM. But it's important to set them as long as index
0 and 1 are present and indicate that SGX is supported.

Instead of passing the GuestMemoryMmap directly to the CpuManager upon
its creation, it's better to pass a reference to the MemoryManager. This
way we will be able to know if SGX EPC region along with one or multiple
sections are present.

The SGX EPC region must be exposed through the ACPI tables so that the
guest can detect its presence. The guest only get the full range from
ACPI, as the specific EPC sections are directly described through the
CPUID of each vCPU.

Based on the presence of one or multiple SGX EPC sections from the VM
configuration, the MemoryManager will allocate a contiguous block of
guest address space to hold the entire EPC region. Within this EPC
region, each EPC section is memory mapped.

As the current AArch64 integration test builds kernel every time,
which would take unnecessary time in CI and therefore not ideal.
This commit refactors the AArch64 kernel building strategy to:
1. Keep the Linux kernel source code directory instead of deleting
it everytime after the kernel is built.
2. In integration test script, check if the Linux kernel source
code directory exists. If so use `git fetch && git checkout -f` to
keep the source code always updated, else run `git clone` to get
the source code.
3. Copy config file in and then compile the kernel.

This simplies some of the handling for PCI BARs particularly with
