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).

Fixes: ae1b83c7d572 ("crypto: arm64/sm4 - add CE implementation for GCM mode")
