crypto: mips/poly1305 - enable for all MIPS processors

commit 6c810cf20feef0d4338e9b424ab7f2644a8b353e upstream.

The MIPS Poly1305 implementation is generic MIPS code written such as to
support down to the original MIPS I and MIPS III ISA for the 32-bit and
64-bit variant respectively.  Lift the current limitation then to enable
code for MIPSr1 ISA or newer processors only and have it available for
all MIPS processors.
