cortex_m.c: Use two byte breakpoint for 32bit Thumb-2 request

When GDB requests a breakpoint on a 32bit Thumb-2 instruction it
sends a length of 3 which the current code rejects. Using the
existing two byte breakpoint for this case appears to work fine.

The use of length==3 for this case is mentioned in a few places:
