Subject: Add aarch64 machine types
Adding changes to add RHEL machine types for aarch64 architecture.
Signed-off-by: Miroslav Rezanina <mrezanin@redhat.com>
Rebase notes (4.0.0):
- Use upstream compat handling
Rebase notes (4.1.0-rc0):
- Removed a15memmap (upstream)

- Set numa_mem_supported
Rebase notes (4.2.0-rc3):
- aarch64: Add virt-rhel8.2.0 machine type for ARM (patch 92246)
- aarch64: virt: Allow more than 1TB of RAM (patch 92249)
- aarch64: virt: Allow PCDIMM instantiation (patch 92247)
- aarch64: virt: Enhance the comment related to gic-version (patch 92248)
Rebase notes (5.0.0):
