amdfwtool: make fields unsigned
The value stored in `gen` is only ever `1` or `0`. Storing `1` causes Clang to warn, since the only valid values for a 1-bit int are -1 and 0: ``` amdfwtool.c:1487:27: error: implicit truncation from 'int' to a one-bit wide bit-field changes value from 1 to -1 [-Werror,-Wsingle-bit-bitfield-constant-conversion] 1487 | amd_romsig->efs_gen.gen = EFS_BEFORE_SECOND_GEN; ``` TEST=Rebuilt coreboot; no warning was emitted.
