Following "ANDROID: fips140: eliminate crypto-fips.a build step", the only remaining dependency on LTO is the fact that the part of the module linker script that merges the text and rodata sections and adds some symbols is guarded by '#ifdef CONFIG_LTO_CLANG'. This doesn't actually need to be the case, though. So guard it by alternatively IS_ENABLED(CONFIG_CRYPTO_FIPS140_MOD). Then, remove the dependency of CRYPTO_FIPS140_MOD on LTO_CLANG. (Note: the android14-6.1 kernel currently has LTO disabled, which is part of the motivation for this change. I don't know whether it will stay that way, though.)
