[salt-formulas] Add & enable armband formula

AArch64 specific formula, mostly tweaking nova conf / installing
virtualization layer prerequisites:
- install qemu-efi;
- install vgabios;
- fix missing link for vgabios binary blob;
- nova conf: cpu_model=cortex-a57 (only for virtual deploys);
- nova conf: virt_type=qemu (only for virtual deploys);
- nova compute conf: virt_type=qemu (only for virtual deploys);
- nova conf: pointer_model=ps2mouse since AArch64 has no USB tablet;

+Subject: [PATCH] Allow libvirt to honor root device naming
+
+Current behaviour in upstream nova is for rootfs to be in /dev/vda
+which is the default behaviour when using virtio driver. However when
+other devices are requested either by glance or by CLI, nova ignores
+that naming and still tries to attach to vda which fails.
+
+Manually applied in https://review.openstack.org/#/c/214314/
+
+JIRA: ARMBAND-376
