[PATCH v2 07/13] crypto: mips - move library functions to arch/mips/lib/crypto/

[Eric Biggers <ebiggers@kernel.org>]

From: Eric Biggers <ebiggers@google.com>

Continue disentangling the crypto library functions from the generic
crypto infrastructure by moving the mips ChaCha and Poly1305 library
functions into a new directory arch/mips/lib/crypto/ that does not
depend on CRYPTO.  This mirrors the distinction between crypto/ and
lib/crypto/.
