crypto: mips/poly1305 - incorporate OpenSSL/CRYPTOGAMS optimized implementation

Browse Source 
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.
