By the way, on x86 we already load some ACPI tables through
fw_cfg:

hw/i386/pc_piix.c:    pc_acpi_init("acpi-dsdt.aml");
hw/i386/pc_q35.c:    pc_acpi_init("q35-acpi-dsdt.aml");

so putting all other tables in one place will just make things more
consistent.

Yes, ACPI is messy, and pc-specific, but IMO that's life: it's better to
give guests as much help as we can if it's messy, not push the messiness
out for guests to handle.
