Subject: [PATCH] crypto: inside-secure - select CONFIG_CRYPTO_SM3

Without this symbol, the safexcel driver causes a link error:

drivers/crypto/inside-secure/safexcel_hash.o: In function `safexcel_ahash_final':
safexcel_hash.c:(.text+0x3c4): undefined reference to `sm3_zero_message_hash'

Fixes: 0f2bc13181ce ("crypto: inside-secure - Added support for basic SM3 ahash")
