qemu: load acpi tables from fw_cfg.

Starting with release 1.7 qemu provides acpi tables via fw_cfg.  Main
    advantage is that new (virtual) hardware which needs acpi support
    JustWorks[tm] without having to patch & update the firmware (seabios,
    coreboot, ...) accordingly.

So if we find acpi tables in fw_cfg try loading them, otherwise fallback
    to the builtin acpi tables.
