[Qemu-arm] [PATCH 1/1] mach-virt: Set VM's SMBIOS system version to mc->desc

[Wei Huang <wei@redhat.com>]

Instead of using "1.0" as the system version of SMBIOS, we should use
mc->desc for mach-virt machine type. With this patch, "dmidecode -t 1"
(e.g., "-M virt-2.12,accel=kvm") will show:

    Handle 0x0100, DMI type 1, 27 bytes
    System Information
            Manufacturer: QEMU
            Product Name: KVM Virtual Machine
            Version: QEMU 2.12 ARM Virtual Machine
            Serial Number: Not Specified
            ...

instead of:
    Handle 0x0100, DMI type 1, 27 bytes
    System Information
            Manufacturer: QEMU
            Product Name: KVM Virtual Machine
            Version: 1.0
            Serial Number: Not Specified
            ...
