crypto: mips/poly1305 - incorporate OpenSSL/CRYPTOGAMS optimized implementation
This is a straight import of the OpenSSL/CRYPTOGAMS Poly1305 implementation for MIPS authored by Andy Polyakov, a prior 64-bit only version of which has been contributed by him to the OpenSSL project. The file 'poly1305-mips.pl' is taken straight from this upstream GitHub repository [0] at commit d22ade312a7af958ec955620b0d241cf42c37feb, and already contains all the changes required to build it as part of a Linux kernel module.
