acpi: Add IPMI table entries
Use the ACPI table construction tools to create an ACPI entry for IPMI. This adds a function called build_acpi_ipmi_devices to add an DSDT entry for IPMI if IPMI is compiled in and an IPMI device exists. 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. Signed-off-by: Corey Minyard <cminyard@mvista.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
