crypto: lib/poly1305 - remove INTERNAL symbol and selection of CRYPTO

Browse Source 
Now that the architecture-optimized Poly1305 kconfig symbols are defined
regardless of CRYPTO, there is no need for CRYPTO_LIB_POLY1305 to select
CRYPTO.  So, remove that.  This makes the indirection through the
CRYPTO_LIB_POLY1305_INTERNAL symbol unnecessary, so get rid of that and
just use CRYPTO_LIB_POLY1305 directly.  Finally, make the fallback to
the generic implementation use a default value instead of a select; this
makes it consistent with how the arch-optimized code gets enabled and
also with how CRYPTO_LIB_BLAKE2S_GENERIC gets enabled.
