MIPS: Cleanup break and trap codes.
Very ancient out-of-tree KDB versions were using BRK_KDB code but it's unused in modern kernels since a long time. Delete it. The microMIPS encoding only reserves 4 bits for a trap code so it's time for further weedkilling. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
