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.
