security/tpm: Unify the coreboot TPM software stack
* Remove 2nd software stack in pc80 drivers directory. * Create TSPI interface for common usage. * Refactor TSS / TIS code base. * Add vendor tss (Cr50) directory. * Change kconfig options for TPM to TPM1. * Add user / board configuration with: * MAINBOARD_HAS_*_TPM # * BUS driver * MAINBOARD_HAS_TPM1 or MAINBOARD_HAS_TPM2 * Add kconfig TPM user selection (e.g. pluggable TPMs) * Fix existing headers and function calls. * Fix vboot for interface usage and antirollback mode.
