Add TPM support to coreboot
and initialize the TPM on S3 resume This patch integrates the TPM driver and runs TPM resume upon an ACPI S3 resume without including any other parts of vboot. We could link against vboot_fw.a but it is compiled with u-boot's CFLAGS (that are incompatible with coreboot's) and it does a lot more than we want it to do.
