crypto: arm64/sm4 - fix possible crash with CFI enabled
The SM4 CCM/GCM assembly functions for encryption and decryption is called via indirect function calls. Therefore they need to use SYM_TYPED_FUNC_START instead of SYM_FUNC_START to cause its type hash to be emitted when the kernel is built with CONFIG_CFI_CLANG=y. Otherwise, the code crashes with a CFI failure (if the compiler didn't happen to optimize out the indirect call).
