core/crypto/crypto.c: fix compile errors when _CFG_CRYPTO_WITH_CIPHER=n

Although _CFG_CRYPTO_WITH_CIPHER=n does not seem to be a valid
configuration (both the REE and RPMB FS use AES and at least one has to
be enabled currently), fix build errors triggered by:

  make _CFG_CRYPTO_WITH_CIPHER=n \
       out/arm-plat-vexpress/core/crypto/crypto.o
