    automation: Modify static-mem check in qemu-smoke-dom0less-arm64.sh
    
    At the moment, the static-mem check relies on the way Xen exposes the
    memory banks in device tree. As this might change, the check should be
    modified to be generic and not to rely on device tree. In this case,
    let's use /proc/iomem which exposes the memory ranges in %08x format
    as follows:
    <start_addr>-<end_addr> : <description>
    
    This way, we can grep in /proc/iomem for an entry containing memory
    region defined by the static-mem configuration with "System RAM"
    description. If it exists, mark the test as passed. Also, take the
    opportunity to add 0x prefix to domu_{base,size} definition rather than
    adding it in front of each occurence.
