I've given this some thought, and I don't think it's the right approach. It has the side effect of
having vbios.rs depend on constants that are defined in GSP version-specific header files. It's
also a convoluted way to add just one constant.
So I think I will just keep
/// IFR signature: ASCII "NVGI" as a little-endian u32.
const NV_PBUS_IFR_FMT_FIXED0_SIGNATURE_VALUE: u32 = 0x4947564E;
in vbios.rs
