rG0926566f6f9c: bhyve: allow building device specific ACPI tables
Summary

Some ACPI devices require a device specific acpi table. E.g. a TPM2
device requires a TPM2 table. Use the acpi_device_emul struct to define
such a device specific table.

This can be an assertion.

The name build_table is quite general, so some comment should explain what this callback is for.

No, it can't. A build_table callback isn't used by all acpi_devices. F.e. qemu_fwcfg has no such callback.
