crypto: s390/sha3 - Remove superseded SHA-3 code

Browse Source 
The SHA-3 library now utilizes the same s390 SHA-3 acceleration
capabilities as the arch/s390/crypto/ SHA-3 crypto_shash algorithms.
Moreover, crypto/sha3.c now uses the SHA-3 library.  The result is that
all SHA-3 APIs are now s390-accelerated without any need for the old
SHA-3 code in arch/s390/crypto/.  Remove this superseded code.

Also update the s390 defconfig and debug_defconfig files to enable
CONFIG_CRYPTO_SHA3 instead of CONFIG_CRYPTO_SHA3_256_S390 and
CONFIG_CRYPTO_SHA3_512_S390.  This makes it so that the s390-optimized
SHA-3 continues to be built when either of these defconfigs is used.
