Add an SSDT ACPI table for the TPM device. Add a TCPA table for BIOS logging area when a TPM is being used. The latter follows this spec here: http://www.trustedcomputinggroup.org/files/static_page_files/DCD4188E-1A4B-B294-D050A155FB6F7385/TCG_ACPIGeneralSpecification_PublicReview.pdf This patch has Michael Tsirkin's patches folded in.
