crypto: arm64/aes-neonbs - fix crash with CFI enabled
aesbs_ecb_encrypt(), aesbs_ecb_decrypt(), aesbs_xts_encrypt(), and
aesbs_xts_decrypt() are called via indirect function calls. Therefore
they need to use SYM_TYPED_FUNC_START instead of SYM_FUNC_START to cause
their type hashes to be emitted when the kernel is built with
CONFIG_CFI_CLANG=y. Otherwise, the code crashes with a CFI failure if
the compiler doesn't happen to optimize out the indirect calls.
Fixes: c50d32859e70 ("arm64: Add types to indirect called assembly functions")
