lib/crypto: riscv/poly1305: Import OpenSSL/CRYPTOGAMS implementation
This is a straight import of the OpenSSL/CRYPTOGAMS Poly1305
implementation for riscv authored by Andy Polyakov. The file
'poly1305-riscv.pl' is taken straight from
https://github.com/dot-asm/cryptogams commit
5e3fba73576244708a752fa61a8e93e587f271bb. This patch was tested on
SpacemiT X60, with 2~2.5x improvement over generic implementation.
