MIPS: Use CONFIG_CPU_MIPSR2 in csum_partial.S



The csum_partial implementation contain optimalizations for the MIPS R2
instruction set. This optimization is never enabled however because the
if directive uses the CPU_MIPSR2 constant which is not defined anywhere.

Use the CONFIG_CPU_MIPSR2 constant instead.
