crypto: mips/poly1305 - enable for all MIPS processors

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. Signed-off-by: Maciej W.

Donenfeld <[email protected]> Signed-off-by: Thomas Bogendoerfer <[email protected]>
