Back when we first introduced the DAWR in this commit:
  4ae7ebe952 powerpc: Change hardware breakpoint to allow longer ranges

We screwed up the constraint making it a 1024 byte boundary rather
than a 512. This makes the check overly permissive. Fortunately GDB is
the only real user and it always did they right thing, so we never
noticed.

This fixes the constraint to 512 bytes.
