Enable BootGuard 1.0 for PCR-0 measurement in Firmware on ProDrive Hermes Board

Operation

We are using BootGuard 1.0 in order to generate an Intel authorized Locality 3 PCR-0 measurement of the boot block, which is the self-measured root of trust for the PCR-2 measurements of Coreboot. That is, we are not using its verification feature, which would require to fuse the chip. Because there is no BootGuard profile without verification, we still have to use a dummy OEM Key for signing both the Key Manifest and the Boot Policy Manifest, so that we can get the PCR-0
