Add ACPI tables for TPM 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.

tpm: add CRB device tpm_crb is a device for TPM 2.0 Command Response Buffer (CRB) Interface as defined in TCG PC Client Platform TPM Profile (PTP) Specification Family “2.0” Level 00 Revision 01.03 v22. The PTP allows device implementation to switch between TIS and CRB model at run time, but given that CRB is a simpler device to implement, I chose to implement it as a different device. The device doesn't implement other locality than 0 for now (my laptop TPM doesn't either, so I assume this isn't so bad) Tested with some success with Linux upstream and Windows 10, seabios & modified ovmf. The device is recognized and correctly transmit command/response with passthrough & emu. However, we are missing PPI ACPI part atm.
