This is the same place that the ACPI SSDT table gets added, so that
devices can add themselves to the SMBIOS table.

This will let things in other files (like IPMI) build SMBIOS tables.

Use the new ACPI table construction tools to create an ACPI
entry for IPMI. This adds a function called from build_dsdt
to add an DSDT entry for IPMI if IPMI is compiled in and has
registered firmware. It also adds a dummy function if IPMI
is not compiled in.
This conforms to section "C3-2 Locating IPMI System Interfaces in
ACPI Name Space" in the IPMI 2.0 specification.
