Enabling CONFIG_HYPERV in the Linux Kernel allows
guest to use hyperv clock source. This changes
improves guest performance. Without this changes
we saw slowness in the guest on MSHV.

Since using the VIRTIO configuration to expose the virtual IOMMU
topology has been deprecated, the virtio-iommu implementation must be
updated.
In order to follow the latest patchset that is about to be merged in the
upstream Linux kernel, it must rely on ACPI, and in particular the newly
introduced VIOT table to expose the information about the list of PCI
devices attached to the virtual IOMMU.

Removing the ISA DMA configurations prevents the kernel from accessing
the port I/O 0x87, which was generating the following warning:
WARN:vmm/src/cpu.rs:378 -- Guest PIO read to unregistered address 0x87
Removing the TELCLOCK configuration prevents the kernel from accessing
the port I/O reserved for the memory manager, which was causing the
following warning:
WARN:vmm/src/memory_manager.rs:289 -- Unexpected offset for accessing
memory manager device: 15

In order to facilitate the memory hotplug for our users, let's enable
the automatic memory onlining in our guest kernel by activating the
kernel config option 'CONFIG_MEMORY_HOTPLUG_DEFAULT_ONLINE'.

Updating the kernel from 5.6-rc4 to 5.8-rc4 allows us to remove the
dependency on both virtio-vsock and virtio-mem patches as they are now
part of the upstream kernel. We're still carrying virtio-iommu and
virtio-fs patches.

This commit adds supporting components and code for enabling the
AArch64 integration tests, including:
1. A Linux kernel config file to build kernel on AArch64 machines.
2. Refactoring the `run_integration_test.sh` to architecture
specific scripts for readability.
