vendorcode/eltan/security: Align mboot with coreboot tpm
Align the eltan mboot support with coreboot tpm support to limit the amount of custom code.
We now only support SHA256 pcrs, only single a single digest will be handled in a call.
The pcr invalidation has been changed fixed values are now loaded while the correct algortihm is
selected.
