[RFC PATCH 08/21] arm64/crypto: Add types to indirect called assembly functions

[Sami Tolvanen]

With CONFIG_CFI_CLANG, assembly functions indirectly called from C code
must be annotated with type identifiers to pass CFI checking. Use
SYM_TYPED_FUNC_START for indirectly called functions in the crypto code.
