Karthikeyan Ramasubramanian 24b5227091 util/amdfwtool: Support multiple firmware identifier types
Currently this tool generates a hash table to verify signed binaries,
with a 2 byte FWID as the only kind of identifier. Going forward some
binaries are going to adopt 16 byte UUID identifiers and more binaries
will follow in the future SoCs. Hence add support for handling multiple
firmware identifier types. While at this remove the unused fwid from the
PSP FW table.

TEST=Build BIOS image and boot to OS in Myst & Skyrim.
