  - deploy: remove gic version in arm vm template

    GIC version is set to v2 in current Arm VM template, but ThunderX
    only supports GICv3 which results in the failure to start VM. This
    patch removes GIC version definition and let libvirt to figure out
    the default value based on host system.
