Subject: [PATCH 12/12] fscrypt: Drop obsolete recommendation to enable optimized NHPoly1305

CONFIG_CRYPTO_NHPOLY1305_NEON, CONFIG_CRYPTO_NHPOLY1305_SSE2, and
CONFIG_CRYPTO_NHPOLY1305_AVX2 no longer exist.  The equivalent
optimizations are now just enabled automatically when Adiantum support
is enabled.  Update the fscrypt documentation accordingly.
