Subject: [PATCH] Provide basic data for AArch64 support matrix/functionality

Nova has two pages in documentation listing things supported on several
architectures/hypervisors. This patch adds initial state of AArch64
into support matrix.

Document minimal qemu/libvirt for aarch64. Version 3.6.0 was first one
which worked for us with Nova without a need for extra patches.
