This is a straight import of the OpenSSL/CRYPTOGAMS Poly1305 implementation
for MIPS authored by Andy Polyakov, and contributed by him to the OpenSSL
project. The file 'poly1305-mips.pl' is taken straight from this upstream
GitHub repository [0] at commit 57c3a63be70b4f68b9eec1b043164ea790db6499,
and already contains all the changes required to build it as part of a
Linux kernel module.

Hi Ard,
Is it also an option to include my mip32r2 optimized poly1305 version?
Below the results which shows a good improvement over the Andy
Polyakov version.
I swapped the poly1305 assembly file and rename the function to
<func_name>_mips
