Extract the SHA-384 hash, RSA public key, and RSA signature from the
FMC ELF32 firmware sections. FSP Chain of Trust verification needs
these to validate the FMC image during boot.

FSP is the Falcon that runs FMC firmware on Hopper and Blackwell.
Load the FMC ELF in two forms: the image section that FSP boots from,
and the full Firmware object for later signature extraction during
Chain of Trust verification. Declare the FMC image in the module's
firmware table so it is bundled for FSP-based chipsets.
