Subject: 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.
