ANDROID: GKI: remove CONFIG_CRYPTO_SHA512_SSSE3 from gki_defconfig

In commit 484c1811 ("lib/crypto: x86/sha512: Migrate optimized
SHA-512 code to library") the sha512 code was moved to a library, and
the Kconfig option was removed as it's not needed anymore.  Remove it
from the gki_defconfig files so that it will continue to build properly.
